Description

CONCENTRATOR FOR THE DISTRIBUTION OF FIBERS, WITH A SWINGING FRAME AND MODULAR COMPLETION PANELS BACKGROUND Passive optical networks are becoming predominant, in part because service providers want to provide high bandwidth capabilities to customers. Passive optical networks are a convenient selection for providing high-speed communications data, because they may not employ active electronic devices such as amplifiers and repeaters between a switchboard and a subscriber termination. The absence of active electronic devices can reduce the complexity of the network and / or the cost and can increase the reliability of the network. Figure 1 illustrates a network 100 that displays lines of passive optical fibers. As shown, network 100 may include a switchboard 101 that connects a number of end subscribers 105 (also called end users 105, here) in a network. The switchboard 101 can additionally connect to a larger network such as the Internet (not shown) and a public switched telephone network (PSTN = public switched telephone network). Network 100 may also include hubs fiber distribution (FDHs = fiber distribution hubs) 103 that have one or more optical separators (for example the 8 separators, the 16 separators or the 32 separators) that generate a number of individual fibers that can lead to the installations of an end user 105. The various lines of the network 100 can be aerial or housed within underground conduits. The portion of the network 100 that is closest to the switchboard 101 is generally referred to as the region Fl, where Fl is the "feeder fiber" of the switchboard 101. The portion of the network 100 closest to the end users 105 can be referred to as a portion F2 of the network 100. The network 100 includes a plurality of transition locations 102 in which the branch cables are separated from the main cable lines. The branch cables are often connected to deployment or reduction terminals 104 which include connector interfaces to facilitate coupling of the fibers of the branch cables to a plurality of different subscriber locations 105. The spacers used in a FDH 103 can be accept a feeder wire Fl that has a number of fibers and can separate those input fibers by example in 216 to 432 individual distribution fibers that may be associated with a similar number of end user locations. In typical applications, 1 optical separator is provided pre-packaged in an optical spacer module housing and is provided with a separation outlet in flexible cables extending from the module. The flexible output cables of the separator are typically applied to the appropriate network cabling connectors with for example SC, LC or LX.5 connectors. The optical separator module provides protective packing for the optical separator components in the housing and thus provides easy handling for otherwise fragile separator components. This modular approach allows the optical spacer modules to be incrementally added to FDHs 103 as required. COMPENDIUM Certain aspects of the description refer to fiber optic cable systems. In exemplary systems, a fiber distribution system includes one or more concentrators for fiber distribution (FDHs) that provide an interface between the switchboard and the subscribers.

Certain aspects of the invention relate to wire routing configurations. Other aspects of the invention relate to improved access and scalability through the use of modular subscriber termination components and modular spacers.

DETAILED DESCRIPTION Now with reference to Figures 2-7, an exemplary fiber distribution concentrator (FDH) 200 is illustrated in accordance with the principles of the present invention. The FDH 200 includes a cabinet 201 that houses internal components. The cabinet 201 includes openings through which a feeder cable (e.g., cable Fl) 700 and a subscriber cable 708 enter and exit the cabinet 201 (see Figure 2C). A swing frame 300 is pivotally mounted on hinges 355 within the cabinet 201. The swing frame 300 includes a screen 301 that divides the swing frame 300 in a front position 302 (see Figure 4) and a rear portion 304 (see Figure 2C). The screen 301 includes a main panel 310 having a termination region 311 and a storage region 313. In general, at least one termination module 400 (see Figures 13A and 13B) is provided in the termination region 311 and at least a storage module 600 (see Figure 9) is provided in the storage region 313. In some embodiments, the screen 301 also includes a secondary panel 315 located adjacent to the main panel 310 and configured for cable management. One or more feeder cable interfaces 800 may be located within the rear portion of the oscillating frame 300. At least one spacer module housing 322 that houses one or more spacer modules 500 is located in the upper part of the oscillating frame 300. FIG. is a schematic diagram showing an exemplary cable routing scheme for the FDH 200. The FDH 200 generally manages connections in a termination panel between input fibers and output fibers in an outdoor plant environment (OSP = Outside Plant) . As it is used here, "a connection" between fibers includes both direct connections as indirect. Examples of input fibers include feeder cable fibers entering the cabinet and intermediate fibers (eg flexible cables applied to the appropriate network cabling connectors extending from separators and bridges / patch fibers) that connect the cable fibers feeder to the termination panel. Examples of output fibers include the subscriber fiber cables that exit the cabinet any intermediate fibers connecting the subscriber cable fibers to the termination panel. The FDH 200 provides an interconnection interface for optical transmission signals at a site in the network, where re-configuration and operational access are desired. For example, as noted above, the FDH 200 can be used to split or separate the feeder cables and terminate the divided feeder cables in distribution cables directed at subscriber sites. In addition, the FDH 200 is designed to accommodate a range of alternate sizes and fiber counts and support factory installation of flexible cables, fan outlets and separators. As shown in Figure 3, a feeder cable 700 is initially routed to the FDH 200 through the cabinet 201 (for example typically through from the back or bottom of the cabinet 201 as shown in Figure 2C). In certain embodiments, the fibers of the feeder cable 700 may include planar fibers. An exemplary feeder cable 700 may include twelve to forty-eight individual fibers connected to a service-providing control unit 101. In some embodiments, after entering the cabinet 201, the feeder cable fibers 700 are directed to an infeed cable 800 ( for example fiber optic adapter modules, a separation tray, etc.). At the feeder cable interface 800, one or more of the fibers of the feeder cable 700 are individually connected to separate separator feed fibers 702. The separator feed fibers 702 are routed from the feeder cable interface 800 to the spacer module housing 322 In the separator module housing 322, the separator feed fibers 702 are connected to the separate separator module 500, wherein the supply fibers 702 each are divided into multiple flexible connectors 704, each having ends with connectors 706. In other embodiments, however, the fibers of the feeder cable 700 can be applied to the appropriate network cabling connectors and addressed directly to spacer modules 500 in this manner overcoming or eliminating the need for an intermediate feeder cable interface 800. When the flex cables 704 are not in service, the ends applied to the appropriate network wiring connectors 706 can be stored temporarily in a storage module. 600 which is mounted in the storage region 313 of the swing frame 300. When the flexible cables 704 are required for service, the flexible cables 704 are routed from the separator modules 500 to a termination module 400 that is provided in the region of termination 311 of the swing frame 300. In the termination module 405 the flexible cables 704 are connected to the fibers of a distribution cable 708. The termination panel is the dividing line between the input fibers and the output fibers. A typical distribution cable 708 forms the portion F2 of a network (see Figure 1) and typically includes a plurality of fibers (eg 144, 216 or 432 fibers) that are routed from the FDH 200 to subscriber sites 709. In some embodiments, one or more of the fibers of the feeder cable 700 are not connected to any of the separator modules 500. On the contrary, these fibers of the feeder cable 700 are connected to through fibers 712 have ends applied to the appropriate network cabling connectors 714. The through fibers 712 are connected to the termination modules 400., without first connecting with the spacer modules 500. By refraining from separating a fiber 712, a stronger signal can be sent to one of the subscribers. The ends applied to the appropriate network cabling connectors 714 of the through fibers 712 can be stored in the storage region 313 when they are not in use. Again with reference to Figures 2A-2C, the FDH 200 cabinet 201 includes an upper panel 202, a lower panel 203, a right side panel 204, a left side panel 206, a rear panel 205 and at least one front door . In some embodiments, the front door at least includes a right door 210 and a left door 212. In one embodiment, the front doors 210, 212 include a lock 211. The front door is at least rotatably mounted to the cabinet 201 using hinges 214, 216, to facilitate access to the assembled components within the cabinet 201. In general, the 201 cabinet of FDH 200 is configured to protect the internal components from rain, wind, dust, rodents and others. pollutants However, the cabinet 201 remains relatively light for easy installation, and breathes to prevent moisture buildup in the unit. In some embodiments, an aluminum construction with a strong powder coating finish also provides corrosion resistance. In an exemplary embodiment, cabinet 201 is made of aluminum of the past caliber, and is NEMA-4X rated. In other embodiments, however, other materials may also be employed. In accordance with exemplary modalities, the FDH 200 is provided in pole mounting or pedestal mounting configurations. For example, as shown in Figure 2, loops 218 may be provided in cabinet 201, to facilitate deployment of the cabinet 201 in a desired place. The loops 218 can be used to locate the cabinet using a crane. In particular, the crane can lower the cabinet 201 in an underground region. In some embodiments, the loops 218 are removable or can be adjusted so as not to project from the upper cabinet panel 202. Still with reference to Figures 2B-2C, the FDH 200 tilting frame 300 includes an upper panel 320, a lower panel 330 , a side panel Right 340 and a left side 341, a hinge mounting strip 350 is located on the left side 341 of the swing frame 300. As illustrated in Figure 4, the screen 301 further includes a connection panel 319 connecting the main panel 310 with the hinge-mounted strip 350. As best shown in Figure 4, a portion 325 of the secondary panel 315 extends upward beyond the upper panel 320 of the swing frame 300. The bulkhead 301 extends vertically "between the panels. upper and lower 320, 330 laterally between the right side panel 340 and the left side 341. In some embodiments, the hinge mounting strip 350 of the swing frame 300 is mounted in the FDH 200 cabinet 201 using one or more hinges 355. The hinges 355 allow the entire tilting frame 300, including the termination modules 400, the storage modules 600, the feeder cable interface device 800 and the spacer modules 500, are rotated out of the front doors 210, 212 of the cabinet 201 to allow access to the optical components in the rear portion 304 of the swing frame 300, for cleaning, testing, maintenance, additions, etc. The rotation of the frame Tiltable 300 outside the cabinet 201 causes the right side panel 340 of the swing frame 300 to move away from the interior volume of the cabinet 201. In some exemplary embodiments, the swing frame 300 can be rotated 90 degrees or more, out of the cabinet 201. In some embodiments, the hinges 355 of the tilting frame 300 locate to provide a single flexion point for the fiber cable directed to the tilting frame 300. This hinge point is constructed to control the folding of fibers. In particular, the hinges 355 and the cable management devices, which are discussed in more detail here, are designed to ensure that the bending radius recommended by the manufacturer is maintained when the swing frame 300 is opened or closed. In one embodiment, the cabinet 201 may be configured in a factory, or plant, to have bundles of cables coated around the hinges 355. The pre-configured cabinet 201 reduces the possibility of wiring being incorrectly made. When the swing frame 300 is in the open position, as shown in Figure 2C, there is access to the components in the rear portion 304 of the swing frame 300. For example, a rear side of the main panel 310 and a rear side of the secondary panel 315 are accessible. In addition, the spacer modules 500 located in the housing of the spacer module 322 (see Figure 4) are accessible through the open top portion of the swing frame 300 when the swing frame 300 is rotated out of the cabinet 201. In contrast, when the tilting frame 300 is in the closed position (see Figure 2B) only the components on the front portion 302 of the swing frame 300 are easily accessible. In exemplary embodiments, the swing frame 300 includes a release latch (not shown). ) which locks the swing frame 300 in a closed position within the cabinet 201 of FDH 200 until the lock is actuated. Once the bolt is actuated, the swing frame 300 can be rotated out of the cabinet 201. In addition, a rotary locking member (not shown) can be mounted to the rear side 304 of the swing frame 300 to keep the swing frame 300 in the open position . With reference to Figures 4-5, the storage region 313 of the tilting frame 300 locates below the termination region 311. In others embodiments, however, the storage region 313 may be on or adjacent to the termination region 311. In general, the termination region 311 defines at least one rectangular opening 312 through which adapters 450 extend (see Figures 13A- 13B) of a termination module 400. The termination modules 400 are described in greater detail here. In the embodiment shown in Figure 4, the termination region 311 includes two columns of openings 312 with each column including twelve elongated slots. 'Strips 309 separate the openings 312 from each column and provide surface area for adhering labeling information (for example connector designation). The storage region 313 also defines one or more openings 314 in which storage modules 600 are mounted (see Figure 9). The storage modules 600 are described in greater detail here. The screen 301 bifurcates the lower panel 330 in a front portion 331 (see Figure 4) and a rear portion 336 (see Figures 2C and 14). In general, the front portion 331 of the bottom panel 330 projects forward of the screen 301. In some embodiments, the front portion 331 is further divided into a first front portion 332 and a second front portion. 334. Each front portion 332, 334 includes a flange 333, 335, respectively projecting substantially perpendicular from the lower panel 330. The front portion 331 of the lower panel 330 thus forms a channel configured to retain clearance or excess fibers from the storage region 313 or from the secondary panel 315. edge 337 of the first front portion 332 is angled to allow the swing frame 300 to rotate opening without channel interference. As best shown in Figures 4 and 6, the partition divides the side panel 340 into front and rear flanges 342, 344 respectively. The front flange 342 extends forward of the secondary panel 315 and the rear flange 344 extends rearward of the secondary panel 315. The rear flange 344 extends from the bottom panel 330 to a bend limiter 962 extending from the top panel 320. The front flange 342 extends from the lower panel 330 beyond the upper panel 320 to the projecting portion 325 of the secondary panel 315. In some embodiments, the front flange 342 includes a front portion 344 substantially parallel to the rear flange 344 and an angle portion 343 extending between the portion projection 325 of the secondary panel 315 and the front portion 344. As best shown in Figure 7, the upper panel 320 of the swing frame 300 is substantially rectangular. Upper panel 320 includes front and rear edges 326, 327. Flanges 323, 324 (see Figure 4) project upwardly from edges 326, 327, respectively. The top panel 320 also has a first end 328 adjacent the side 341 and a second opposite end 329 adjacent the side panel 340. A radius of curvature limiter 940 extends upwardly from the first end 328. In some embodiments, a portion of the end 329 of upper panel 320 defines a width of a channel B with front flange 342 of side panel 340. The end portion 329 defining channel B ends before reaching the remaining portion of end 329. The depth of channel B is extends from the secondary panel 315 to the flange 335 of the second front portion 334 of the lower panel 330. The spacer module housing 322 of FDH 200 is located in the upper panel 320 adjacent the first end 328. The spacer module housing 322 serves to protect, organize and secure the modules 500 FDH separators 200. The housing of the separator module 322 can be constructed in various sizes, to accept different numbers of spacer modules 500. The spacer module housing 322 is generally rectangular and defines one or more locations within the open interior sized to accept one. or more optical separator modules 500. To accept 500 separator modules, the module housing 322 includes a structure for supporting / securing the spacer modules 500. In exemplary embodiments, the spacer modules 500 are designed to couple by rapid actuation in the spacer module housing 322. In one embodiment, the spacer modules 500 are they load into the housing of the separator module 322 from the front to the rear (i.e. from the side opposite the end 329 to the side facing the end 328). The module housing 322 is further configured to allow the spacer modules 500 to receive a power fiber such as the fiber 702 of Figure 3, at one end of the spacer module 500 and to output multiple fibers, such as flexible cables 704. of Figure 3, from the opposite end of the spacer 500.

Now with reference to Figures 8A-8C, one type of spacer module 500 that can be mounted in the housing of spacer module 322 is a spacer having an integral connector. Figure 8A is a left side view of this spacer module 500. The spacer module 500 includes a housing 505 having at least one protective sheath 510 projecting forward and at least one integral connector 520 projecting backward. In the embodiment shown, two sleeves 510 project from the front and two integral connectors 520 project backward from the spacer housing 505. In an exemplary embodiment (not shown), each spacer has four integral connectors 520. In some embodiments , a handle 540 is also projected from the front end of the spacer housing 505. Figure 8B is an exploded view of the spacer module 500 of Figure 8A showing the internal components of the spacer module 500. Figure 8C shows a cross section of the module separator 500 of Figure 7A inserted into the housing of spacer module 322. An adapter assembly 530 is secured in the housing of spacer module 322, using a fastener 536. In a In this embodiment, the adapter mounts 530 are mounted on the rear side of the spacer module housing 322. The adapter assembly 530 is configured to receive the connectors 520 of the spacer module 500, when the spacer module is inserted in the spacer module housing 322. As shown, the adapter assembly 530 is further configured to receive an opposite connector associated with the feeder cable 700. In some embodiments, the adapter assembly 530 receives a connector 703 terminating a separator feed fiber 702. In other embodiments, the assembly adapter 530 receives a connector 701 terminating feeder cable 700 itself. In this way, feeder cable fibers 700 can be easily coupled to spacer modules 500. Other embodiments of spacer modules 500 do not include integral connectors 520. In these embodiments, Adapter mounts 530 are not mounted in the housing of the separator module 322 and the power cables 700 can not be plugged directly into the separator modules 500. Conversely, flexible power cables (not shown) pass through the spacer housing 505 and enter the spacer module 500. The opposite ends of the cables Flexible power supplies may or may not be applied to the appropriate network cabling connectors. If the ends 701 terminate in connectors (not shown), then the supply fibers 702 are placed at the interface with the feeder cable 700 using an adapter module 810 (see Figure 18). If the ends 701 do not apply the appropriate connectors to network cabling, then the supply fibers 702 are spliced with the feeder cable 700 using a pallet tray 808 (see Figure 19). Typically, each spacer module 500 receives between 1 and 4 fibers and outputs between 2 and 16 fibers 704 for each feed fiber. In an exemplary embodiment, four feed fibers 702 enter a separator module 500 and thirty-two flexible cable fibers 704 exit the separator module 500. Further information regarding the separator module 500 can be found in the application of US Pat. that has file to the agent number 2316.2314US01, with title "Fiber Optic Splitter Module", that was presented on a date concurrent with the present, and that here preference is incorporated. Additional information of other types of spacer modules can be found in the US patent application.

Serial Number 11/138063, filed on May 25, 2005, under the title "Fiber Optic Splitter Module"U.S. Patent Application Serial Number 11/215837, filed on August 29, 2005, under the title" Fiber Optic Splitter Module With Connector Access; "and U.S. Patent Application Serial Number 11/321696, filed in December 28, 2005, with the title "Splitter Modules for Fiber Distribution Hubs", the descriptions of which are hereby incorporated by preference.Now with reference to Figures 9-10, the separator modules 500 and storage modules 600 can be added in Incremental shape to the tilting frame 300. Figure 9 illustrates a spacer module 500 having multiple flexible connectors to which appropriate mains connectors 704 are applied emerging from a protective sheath 510 in the spacer module 500. Flexible cables with connectors Suitable network cabling 704 are typically stored in one or more storage modules 600 prior to installation in the tilt frame 300. In some embodiments, the connector 706 of each flexible cable 704 is secured in a storage module 600 before the separator module 500 leaves the factory. Typically, flexible cables with connectors appropriate to network cabling 704 of each spacer module 500 are directed to four storage modules 600 each containing eight connectors. The storage module 600 includes a body 610 having a front side 602 and a rear side 604. The body 610 is configured to support at least one fiber connector 706. Typically, the body 610 is configured to hold approximately 8 connectors 706. In some embodiments, the body 610 is arranged to retain the fiber connectors 706 in a single-row configuration. In other embodiments, the body 610 may be arranged to hold the connectors 706 in a square pattern or in any other desired configuration. More information regarding the storage modules 600 can be found in the U.S. patent application. Serial number 10 / 610,325, filed on June 30, 2003, entitled "Fiber Optic Connector Holder and Method"; US patent application Serial number 10 / 613,764, filed on July 2, 2003, with the title "Telecommunications Connection Cabinet"; and US patent application. Serial number 10 / 871,555, presented on June 18, 2004, entitled "Multi-position Fiber Optic Connector Holder and Method", the descriptions of which are incorporated herein by reference. In some embodiments, the body 610 is designed to engage by rapid actuation in one of the openings 314 defined in the storage region 313 of the main panel 310. The openings 314 may be arranged in any desired configuration within the storage region 313 of the panel main 310. In the example shown in Figure 10., storage region 313 of main panel 310 defines nine openings 314 in a rectangular pattern. Each opening 314 is configured to receive a storage module body 610 arranged to retain eight fiber connectors 706 in a row. As shown in Figure 10, when the separator module 500 is loaded into the housing of the separator module 322 during installation , the corresponding storage modules 600 are loaded in the storage region 313 of the main panel 310. For ease of observation, only a separator 500 having a flexible cable 704 and a storage module 600 is illustrated. The flexible cable 704 is extended from the separator module 500 to the storage module 600, is directed from the protective case 510, through the upper panel 320, going down in channel B on the front side of the secondary panel 315, and through the lower panel 330 of the swing frame 300. To achieve this addressing, the top panel 320 and the secondary panel 315 include cable management arrangements. In some embodiments, the cable management arrangements in the upper panel 320 include a first reel 952 located between the spacer housing 322 and the radius of curvature 962 and a second reel 954 located between the bending limiter 940 and the front flange 342. Flexible cables 704 exiting the separator 500 are first wrapped or wound around the first reel 952 and then around the second reel 954. A radius of curvature limiter 964 having tabs 965 extending downwardly from the upper panel 320, partially defines the B-channel. From the second reel 954, some of the flexible cables 704 are directed over the bending limiter 964 and inside the B-channel. In some embodiments, a partial fiber reel 966 is mounted to extend from the projecting portion 325. of the secondary panel 315 and also oriented to direct fibers within the B channel. To avoid excessive or matted weight of the fibers 704, some of the fibers 704 can be directed in channel B on the partial reel 966 instead of the 964 curvature limiter, the extra clearance can also be absorbed by directing the flexible cables 704 on the reel 966 instead of excessive bending limiter 964. A bending limiter 968 can also be mounted on the projecting portion 325 of the secondary panel 315 and oriented to direct fiber upwards to the partial reel 966. The front of the second panel 315 includes at least one row of partial reels 970 and at least one row of radio limiters 980. In an exemplary embodiment, the partial reels 970 are oriented to allow directed fiber going down the channel B, wrap at least partially around one of the reels 970. The fiber can run from the partial reels 970 either on the lower panel 330 to the storage modules 600 or on the limiters 980 to the termination modules 400. 980 limiters are oriented to allow directed fiber from the partial reels 970 to travel to the termination modules 400 without excessive bulging. Now with reference to Figure 11, when a flexible cable 704 retained in a storage module 600 will be connected to a line of subscriber distribution 708, the corresponding connector 706 is removed from the storage module 600 and transferred to the appropriate adapter 450 in a termination module 400. During this transfer process, the fiber may need to be rewound around a different partial reel 970 , such as the partial reel 972, in order to reach the adapter 450. From the partial reel 972, the fiber can be routed around a convenient limiter 980 to avoid excessive bending before reaching the adapter 450. In some embodiments, the fiber is also fed through supporting fingers 990 extending from the termination section 311 of the main panel 310, before plugging into the adapter 450. When all the fibers 704 originally held or secured in the storage module 600 have been directed to the Subscriber termination modules 400, the empty storage modules 600 can be removed to make room for a new separator module 500 and new storage modules 600. Now with reference to Figures 12A-12B, as time passes and the number of subscribers increases, a user can add terminating modules 400 to the tilting frame 300. FIGS. 12A and 12B show an example of a termination module 400. The termination module 400 includes a termination branch 410 and a management branch 420, arranged in a substantially L configuration. In some embodiments, a joint section 430 connects the termination branch 410 to the branch or management branch 420. In other embodiments, the hinge section 430 is monolithically formed with either the termination branch 410 or the management branch 420. In still other embodiments, the termination branch 410, the operating branch 420, and the hinge section 430 they form monolithically (for example, they are built as a single piece of folded sheet material). In some embodiments, a front side of the termination branch 410 of the termination module 400 (shown in Figure 12B) is mounted on the rear side of the main panel 310. In one embodiment, the termination branch 410 is mounted on the panel In other embodiments, however, other fasteners such as bolts, rivets, nails and other such devices can be used to connect the module 400 to the main panel 310. In still other embodiments, the module 400 can be connected to the main module 310. Main panel 310 using adhesive.

Each termination module 400 includes at least one row of fiber optic adapters 450 for connecting the fibers of the main cable 700 to the fibers of the distribution cable 708. Each adapter 450 has a front end 452 and a rear end 454. The front end 452 of each adapter 450, is configured to retain a connector 714 of a fiber 712 interfaced with the main line 700, or the connector 706 of a split fiber 704 of the main line 700. The rear end 454 of each adapter 450 is configured to retain a connector 710 of a distribution cable fiber 708. The adapters 450 project through the terminating branch 410 such that the connectors 706 enter the front ends 452 of the adapters 450 from a front side of the panel main 310 and connectors 710 of distribution cable 708 enter adapters 450 of a rear side of main panel 310. In the illustrated embodiment a, each module 400 includes six horizontal rows of adapters 450 cooperating to define two banks of side-by-side adapters. When the module 400 is mounted on the main panel, the front side of the branch 410 buttresses against the rear side of the main panel 310, and the rows of adapters 450 project towards forward, through the corresponding horizontal slots 314 defined by the panel 310. The operating branch 420 extends rearward from the termination branch 410. Each management branch 420 includes an appropriate number of fan outlets 424 to accommodate the number of adapters 450 in the module 400. For example, in one embodiment, the termination branch 410 of a module 400 includes six rows of adapters 450, each row has twelve adapters 450, and the management branch 420 includes six fan outputs 12: 1, 424. As the term is used here, a 12: 1 fan output is configured to receive twelve optical fibers and output a single flat cable containing the twelve fibers. In another mode, nine fan outputs of 8: 1 or three fan outputs of 24: 1 can be provided instead of the 12: 1 fan outputs. Still in other embodiments, the fan outlets can be used to line up the fiber. In some embodiments, the termination module 400 is pre-wired at the factory to include a distribution fiber with appropriate network wiring connectors 708, coupled to each adapter 450. Dust caps 453 are generally provided at the front ends 452 of the 450 adapters for protect the finished distribution fibers 708 from dust, dirt and other contaminants. The connector 710 of each distribution fiber is mounted within the rear end 454 of an adapter 450 and the distribution fibers 708 are routed from the connector 710 to the fan outlets 424 that are provided in the management branch 420 of the termination module. 400. Still in other embodiments, the termination module 400 is not pre-wired and dust caps 455 are provided at the rear ends 454 of the adapters 450 to protect the adapters 450. In some embodiments, the management branch 420 of the module 4 termination 400 also includes at least one cable management device 425 to handle the excess fiber length of distribution fibers 708. In general, in these systems, fibers 708 are first directed to cable handling devices 425 and after towards the fan outlets 424. Examples of 425 cable management devices include a reel of fibers, one or more limiters of bending radius, one or more fiber clamps and other of these devices. In the examples shown, the management branch 420 includes a reel of fibers 426 formed of two radius bending limiters. Each radio bending limiter includes a flange 427 for retaining the fiber on the reel 426. In some embodiments, one or more fiber-wire clamps 428 for retaining fiber cables may be spaced between the radius bending limiters of the reel 426. Now with reference to Figure 13, the handling branch 420 of the termination module 400 includes an opening 422, through which the fibers are routed from the cable management devices 425 to the fan outlets 424. As the fan outlets 424 exit, the flat fibers are directed to a Cabinet fan output (not shown) or other device. inferióase of cable. In other embodiments, the fan outlets 424 are provided on the same side of the management branch 420 as the cable management device 425. In these embodiments, the flat fibers are directed from the fan outlets 424 through the openings 422 and towards the cabinet fan exit. The fan-out cabinet is mounted inside the cabinet 201 and not connected to the tilting frame 300. The fan-out cabinet can be used to reduce the flat fibers in a single cable terminal jacketed leaving FDH 200. The cable terminal it is spliced with a subscriber distribution cable outside of FDH 200. In various embodiments, the terminal cable is in the length range from about 7. 62 to approximately 91.44 meters (approximately 25 to 300 feet). In other embodiments, the distribution cable 708 can be directed to the cabinet 201 and spliced or otherwise connected to the fiber 708. Now with reference to Figure 14, the rear side 304 of the swing frame 300 forms an open chamber adapted to house at least one termination module 400. The open chamber is defined by the partition 301, the upper panel 320, the lower panel 330, and the side panel 340. Figure 14 is a rear perspective view of four termination modules 400 mounted in the open chamber. The 450 adapters have been removed for ease of observation. In other embodiments, any desired amount of termination modules 400 can be mounted on the swing frame 300. The termination modules 400 are configured to mount on the rear side of the termination region 31 1 of the main panel 310. Figure 15 shows a left side view of a tilting frame 300 having four termination modules 400 mounted therein. When multiple termination modules 400 are mounted on the rear side of the main panel 310, the operating legs 420 of the termination modules 400 form a partial side panel opposite the side panel 340. In some embodiments, the operating legs 420 of the modules 400 are fastened to each other or to the swing frame 300. In other embodiments, shown in Figure 15, the modules 400 are attached to the swing frame 300 only in the termination branch 410 and legs of handling 420 are of free floating. Now with reference to Figures 16-19, the swing frame 300 can be configured with different inferring devices 800 (see Figure 3) and the cable management devices, to create multiple fiber paths between the incoming feeder wire 700 and the distribution lines 708. The infernase devices 800 and the handling devices employed in a particular configuration will depend on whether it is convenient to divide the feeder cable 700 and what type of spacer module 500 is used. In some modes, the feeder cable 700 is connected to one or more separator feed fibers 702. In a similar embodiment, a first end 701 of a separator feed fiber 702 is placed with appropriate connectors to the network cabling. Still in another of these modalities, the first extreme 701 is not coupled with appropriate connectors for network cabling. The opposite end 703 of the feed fiber 702 can already form an interface with a integral connector 520 in the separator module 500, such as when the separator module illustrated in Figures 8A-8C is used, or the separator housing 505 may penetrate. In other embodiments, however, the feeder cable 700 has connectors configured to interface with integral connectors 520 of the spacer module 500. FIG. 16 is a rear view of the swing frame 300, adapted to be interfaced to a feeder cable with appropriate connectors for network wiring 700, with a spacer module 500. To achieve this interface, the devices of cable management are arranged in accordance with a Cl configuration. In the Cl configuration, a cable storage reel 922 and one or more partial storage reels 924 are mounted to the side panel 340 of the swing frame 300. A fan exit device 926 is mounted adjacent to the reels 922, 924. 936 radio limiter is mounted from the secondary panel near the corner formed by the top panel 320 and side panel 340. Support fingers 932 projecting downward from the top panel 320 form a path A on which the fibers can be routed from the end 329 of the upper panel 320 to the other end 328. In some embodiments, the supporting fingers 932 include a bracket with multiple prongs 934 having at least two fingers 932, each finger extends in a different direction. In an exemplary embodiment, the multi-barbed fastener 934 includes four fingers 932 located orthogonally to each other. Any excess fiber length can be compensated by winding the flexible cables 702 around the multi-barred fastener 934. A limiter 940 having tabs 945 extends from the upper panel. To connect the feeder cable 700 to the separator 500, the cable 700 is first routed around reels 922, 924 and then to the fan-like output device 926. The fan-like output device 926 separates the fibers of the feeder cable 700 into feed fibers. individual. Any excess length of the individual fibers of the feeder cable 700 can be stored by wrapping the fibers around the reels 922, 924. The fibers of the feeder cable 700 are then routed around the restrictor 936 and over the A path using the supporting fingers 932 projecting downwards from the upper panel 320. The feeder cable 700 is then curved around the limiter 940 extending from the upper panel 320 and directly plugged in at least one of the adapter mounts 530 attached to the module housing separator 322. The fibers of the feeder cable 700 can be protected while being guided within the swing frame 300 by loose buffer tubes. Figure 17 is a rear perspective view of the swing frame 300 adapted to interface a feeder cable with appropriate connectors to the network wiring 700 with a spacer module 500. The cable management devices are arranged in accordance with a variation of the Cl configuration. The storage reels 922, 924 and the fan output device 926 are mounted on the rear side of the secondary panel 315 instead of the side panel 340. In other embodiments (not shown) the storage reels 922, 924 and the fan outlet 926 can mounted on the lower panel 330. Irrespective of the location of the reels 922, 924 and the fan-like output device 926, the feeder cable 700 is still directed from the fan output device 926 to the bending limiter 936, over the route A, on the bending limiter 940 and the adapter assembly 530 mounted on the spacer module housing 322. Now with reference to Figs. 18-19, the feeder cable 700 can interface with separator feeds 702 using at least an interface device 800 instead of connecting directly to the separator 500. FIG. 18 is a rear perspective view of the swing frame 300 configured to interface with a feeder cable with appropriate connectors to network wiring 700, with a spacer module 500 to through the intermediate separator feed fibers 702. Each of the separator feed fibers 702 has a first end with appropriate connectors to network cabling 703 that plugs into one of the adapter mounts 530 opposite the integral connectors 520 of the spacers 500. In other embodiments that do not use a separator having an integral connector, however, the spacer supply 702 is a flexible cable that penetrates the spacer housing 505 instead of being plugged into an adapter assembly 530. Each of the separator feed fibers 702 also has a second end with appropriate connectors to network cable 701 that interface with one end with appropriate network cabling connectors of a fiber feeder cable 700. These flexible power cables 702 are routed from the adapter assembly 530 over the appropriate radius limiter 940 and below the upper panel 320 as shown in Figure 16. In particular, the flexible power cables 702 are routed on route A to side panel 340 using support fingers 932 and then around radio bending limiter 936. The ends 701 of the flexible power cables are then connected to feeder wire 700 using a first adapter module 820. In some embodiments, the first adapter module is mounted on the secondary panel 315 adjacent to the lower panel 330. In other embodiments, however, the first adapter module 820 may be secured to the lower panel 330 or the side panel 340 The first adapter module 820 includes multiple adapters 825 arranged in one or more rows. In some embodiments, each of the rows includes approximately six adapters 825. Additional information regarding adapter module 820 can be found in U.S. patent application. Serial Number 11 / 095,033, filed on March 31, 2005, and with the title "Adapter Block Including Connector Storage;" and in the patents of the U.S.A. Nos. 5,497,444; 5,717,810; 5,758,003; and 6,591,051, the descriptions of which are incorporated herein by reference. In order to connect the feeder cable 700 to the first adapter module 820, additional cable management devices are provided according to a second configuration C2. The second configuration C2 includes a fan output device 901 and one or more fiber reels for full or partial clearance storage 902, 904, respectively. In the example shown, the fan-out device 901 and the storage reels 902, 904 are mounted on the bottom panel 330. The feeder cable 700 is first directed to the fan-out device 901, which separates the fibers from the flat cable 700 in individual fibers. Any excess length of the individual fibers of the feeder cable 700 can be stored in the slack storage reel 902 and the partial slack storage reels 904. The fibers of the feeder cable 700 next to the first adapter module 820. The ends with connectors Suitable for network cabling of the feeder cable 700 are mounted on one end of the adapters 825 of the first adapter module 820. The ends with appropriate connectors to the network cabling 701 of the supply fibers 702 are directed from the radio restrictor 936 to the end opposite of the adapters 825 of the first adapter module 820. The adapters 825 provide an inferium between the connectors of the fibers of the feeder cable 700 and the connectors 701 of the supply fibers 702.

Figure 19 is a rear perspective view of the swing frame 300 configured to be used with a spacer module and a feeder wire 700 having ends without appropriate connectors to the network wiring. The feeder cable 700 is separated with spacer supply fibers 702 having second ends without appropriate connectors to network wiring 701. In order to connect the feeder cable 700 to the fiber feeds without appropriate connectors to network wiring 702, a separation tray 830 is provided and on the rear side 304 of the swing frame 300. In order to connect the feeder wire 700 to the separation tray 830, additional cable management devices according to the third configuration C3 are provided. The third configuration C3 includes a fan-out device 907 and one or more radio bending restrictors 906 mounted around the splice tray 830. Additionally, at least one bending radius limiter 908 is located adjacent to the splice tray. 830. Each restrictor 906 includes a tab 907 for keeping the fibers in a loop around the limiters 906. The limiters 906 are oriented to prevent fiber from trapping at the corners of the splice tray 830. In some embodiments, the splice tray 830 and the limiters 906 are located on the rear side of the secondary panel 315. In other embodiments, however, the splice tray 830 and the limiters 906 can be located or placed in any desired location on the rear side 304 of the tilt frame 300. The ends without connectors appropriate to the network cabling of the feeder cable 700 are routed around the limiters 906 and the splice tray 808. Any excess length of the individual fibers of the feeder cable 700 can be stored by wrapping the fibers around the splice tray 830. The feed fibers 702 from the spacer module 500 are directed from the radio restrictor 936 around the restrictor 908 and into the splice tray 830. The ends without appropriate connectors to the network wiring of the feeder cable 700 are then butted with the ends without proper network cabling connectors 701 of the feed fibers. Still with reference to Figures 16-19, in some embodiments, it may be convenient not to split one or more of the feeder cables 700 to allow transmission of a stronger or more reliable signal to a subscriber. In some embodiments, therefore, the tilting frame 300 is further configured to allow at least one fiber (referred to as a through fiber) 712 to interface with a fiber of the feeder cable 700. The through fiber 712 derives the spacer modules 500 and advances to the front of the tilt frame 300 to interface with a distribution line 708. To accomplish this addressing, the swing frame 300 includes an aperture 910 in the rear flange 344 of the side panel 340. In some embodiments, the aperture 910 includes a radius limiter 912 (as best seen in Figure 13) that is extends outward from the exit surface of the flange 344 to prevent excessive bending of a fiber directed through an opening 910. A tongue 915 may also be pressed outwardly into the rear flange 344 to define a riser channel to the exterior side of the flange. rear flange 344. A radius bending limiter 962 links the rear flange 344 of the side panel 340 to the top panel 320. Hand-held devices are provided. additional cable based on the configuration Cl, C2, C3 with which the tilting frame 300 is disposed. With reference to Figure 17, if the tilting frame 300 is arranged in accordance with the Cl configuration, then the fibers with connectors appropriate to network cabling of the feeder cable 700 is connected to the feed fibers 702 using a second adapter module 810. The adapter module 810 includes multiple fiber optic adapters 815 configured to accept fibers with appropriate connectors to network cabling from either end. The tilting frame 300 also includes additional cable handling in the form of a bend radius limiter 906 and slack storage reels 902, 904. To bypass the spacer modules 500, the feeder wire 700 is still routed around the reels 922 , 924 to the fan output device 926. From the fan output device 926, however, the fibers of the feeder cable 700 are routed back around the reels 922, 924, around bending limiter 926 and then around the reels 902, 904. Of the reels 902, 904, the ends with appropriate connectors to the network wiring of the fibers 700 hold the adapter module 810. The adapter module 810 connects the fibers 700 with ends with appropriate connectors to the network wiring the through fibers 712 which are directed out of the opening 910, going up the side panel 340, over the limiter 962, and over the top panel 320. From the top panel r 320, the through fibers 712 are directed towards the modules of termination 400 as described above, with reference to Figures 10 and 11. With reference to Figure 18, the through fibers 712 can also be used with the second configuration Cl. The feeder cable 700 is still first directed to the fan output device 901 and then to one end of the adapter module 820 with any clearance that is stored in the reels 902, 904 However, instead of flexible spacer cables 702 connecting to the other end of the adapter module 820, the flexible leads 712 are plugged into the adapter module 820. The flexible leads 712 then follow the same pattern of direction as discussed in FIG. the previous paragraph. With reference to Figure 19, the through flexible cables 712 can also be spliced with ends without appropriate connectors to the network wiring of the feeder cable 700. If this configuration is desired, then the tilt frame 300 is provided with the second adapter module 810 discussed above. with reference to Figure 17. The feeder cable 700 is still routed around the limiters 906 and ascending to the splice tray 830 according to the configuration C3. Any excess length of the individual fibers of the feeder cable 700 can be stored by wrapping the fibers around the limiters 906. However, the feeder cable fibers 700 are spliced with flexible cables with appropriate connectors to the 711 res wiring instead of the separation feeders 702. From the splice tray 830, the flexible cables with connectors appropriate to network cabling 711 are directed around storage reels 902, 904 and then plugged into the second adapter module 810. The second adapter module 810 connects the flexible cables 711 with the fibers with appropriate connectors to cabling of through network 712 which are directed out of opening 910, going up side panel 340 to restrictor 962, and on top panel 320. Through-fibers 712 derive separator module 500 and are directed around the second fiber reel 954 of the upper panel 320 and inside channel B either by means of the limiter 964 or the partial reel 966. The direction of the through fiber 712 on the side front 302 of the swing frame, substantially the same as the direction of the flexible spacer wires 704 discussed above with reference to Figures 10 and 11. Typically, a through fiber 712 is immediately connected to a subscriber line 708 by an adapter 450 in a termination module 400. In some embodiments, however, the through fibers 712 can be stored in empty sites in the storage modules 600. The above specification, examples and data provide a complete description of the manufacture and use of the composition of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims added below.
