Each connector is structurally characterized in that the single-core butterfly-shaped optical cable is connected with a back end of a metal tail handle, and the front end of the metal tail handle is connected with the back end of a ceramic insertion core after being sleeved with an SC (square connector) main body and a spring; an optical fiber fibril and a blue core wire which are covered by a stiffener penetrate through a centre hole of the metal tail handle, the optical fiber fibril is connected with the ceramic insertion core; a joint of the single-core butterfly-shaped optical cable and the metal tail handle is in protective fixed connection by an aluminum riveting component, and the joint is sleeved with a plastic sheath; the SC main body is connected with the back end of a plastic inner frame in an embedding mode, so that a connection head which consists of the ceramic insertion core, the metal tail handle, the aluminum riveting component and the single-core butterfly-shaped optical cable is movable relative to the plastic inner frame. The butterfly-shaped optical cable jump fiber disclosed by the invention has the advantages that a hard optical fiber is used as the jump fiber, the optical fiber fibril is protected more effectively, threading and connection are convenient, bending is not overlarge, signals can not be attenuated, and a ready-mad jump fiber is provided for the last section of FTTH (fiber to the home).
Description
Technical field
The present invention relates to the optical-fibre communications equipment technical field, specifically, is a kind of hard optical cable---butterfly optical cable jumping fiber that in Fiber to the home (FTTH), uses.
Background technology
Optical fiber technology is very general in the application of China, and Fiber to the home (FTTH) is one of best measure of efficient in the present fiber optic applications, and it need use many optical fiber dispensing apparatus and parts.After realizing that Fiber to the home, family's broadband access ability can surpass per second 100 megabits, and its application results is very tangible.
Outdoor optical cable is switched to passes through a series of fiber distribution and continue in the each household resident family of residential quarters; At present; In the city or population concentration local floor distributing cabinets that adopt of living more realize, in Fiber to the home process, to use a large amount of tail optical fibers and jumping fiber.From to the fibre-optic terminus at family to still connecting the concrete equipment with optical fiber, that is, in users home, also also have the demand of fibre junction.To this, the method that adopts at present is, connects joint with flexible optical cable and makes jumping fiber and use.But; Because flexible optical cable is made up of the outer coating (sheath) of optical cable, virtue wheel, white heart yearn and optical fiber; The problem that the jumping fiber made from soft fiber (seeing accompanying drawing 1) is easy to generate is: 1. because of the line body too soft when doing engineering cross-under sometimes inconvenient, when wearing especially from lower to upper; 2. flexible optical cable receives the influence of extraneous factor (people, environment) easily, causes bending radius little easily, causes the decay of signal; 3. be that Kev draws material owing to what be provided with between white heart yearn and the outer coating of optical cable; Between certain clearance is arranged, therefore, white heart yearn can be movable in the coating outside optical cable; In other words; The outer coating of optical cable is contractile with respect to optical fiber, because inotropic existence is not enough to the optical fiber protection that connects after fixing sometimes.
Summary of the invention
Of the present inventionly will solve above-mentioned technical matters, for fiber-to-the-home final stage provides a kind of ready-made, butterfly optical cable jumping fiber that need not field fabrication, it adopts hard optical cable to do the line body; The cross-under line is convenient during use, and optical fiber does not allow to be subject to the influence of extraneous factor (people, environment) yet, causes bending radius little; Main is; Hard butterfly sheath is connected with optical fiber closely with blue heart yearn, and is not removable each other, more effective to the protection of optical fiber.
For addressing the above problem, the technical scheme that the present invention takes is:
A kind of butterfly optical cable jumping fiber; Comprise ceramic insertion core, plastic cement housing, plastic cement inside casing, spring, aluminum riveting spare, optical cable and plastic cement sheath; Ceramic insertion core is socketed in the plastic cement inside casing, the outer socket plastic cement housing of plastic cement inside casing, and the plastic cement sheath is socketed in the junction of butterfly optical cable and connector; It is characterized in that said optical cable adopts single core butterfly optical cable, the identical connector of structure is equipped with at the two ends of single core butterfly optical cable; The structure of said connector comprises: ceramic insertion core, metal caudal peduncle, aluminum riveting spare, single core butterfly optical cable, wherein, and structure that single core butterfly optical cable is connected with metal caudal peduncle rear end, the front end of metal caudal peduncle is in socket
SC(Square Connector is translated as: the structure that foursquare connector) is connected with ceramic insertion core rear end (fixing) behind body and the spring; Optical fiber and blue heart yearn pass the mesopore of metal caudal peduncle under the wrapping of reinforcement, optical fiber is connected with ceramic insertion core; Be fixedly connected overcoat plastic cement sheath as protectiveness with aluminum riveting spare with the junction of metal caudal peduncle at single core butterfly optical cable; The interlocking of SC body is in the rear end of plastic cement inside casing, and therefore, the connector that is made up of ceramic insertion core, metal caudal peduncle, aluminum riveting spare, single core butterfly optical cable is movable with respect to the plastic cement inside casing.
Described metal caudal peduncle adopts the copper structural member, and handle is provided with two annular projections.On the annular projection of metal caudal peduncle rear end, be socketed with aluminum riveting spare, aluminum riveting spare overlaps simultaneously catches single core butterfly optical cable, increases the pulling force of single core butterfly optical cable and connector.
On the annular projection of said metal caudal peduncle rear end, be socketed with aluminum riveting spare, aluminum riveting spare overlaps simultaneously catches single core butterfly optical cable, increases the pulling force of single core butterfly optical cable and connector.
The optical property of butterfly optical cable jumping fiber of the present invention requires:
Insert loss: the insertion loss (containing adapter) of arbitrary connector (plug)≤0.30d B (containing repeatability);
Return loss: the return loss＞50dB of arbitrary connector (plug).
The good effect of butterfly optical cable jumping fiber of the present invention is:
(1) adopting hard optical cable---single core butterfly optical cable is made the connection optical cable, according to single core butterfly optical cable design feature (optical fiber is embedded in the optical cable, can not be free movable); The butterfly optical cable connector connects through adapter; After perhaps moving behind the ceramic insertion core, more effective to the protection of optical fiber, and also the cross-under line is convenient in construction; The influence that is not subject to extraneous factor (people, environment) causes bending, also can not cause the decay of signal;
(2) the butterfly sheath is connected with optical fiber closely with blue heart yearn; Not removable each other; The connector that is made up of ceramic insertion core, metal caudal peduncle, aluminum riveting spare, single core butterfly optical cable is mass activity with respect to the plastic cement inside casing; According to single core butterfly optical cable design feature, this protection to optical fiber is more effective;
(3) for fiber-to-the-home final stage provides a kind of ready-made, butterfly optical cable jumping fiber that need not field fabrication, bigger convenience is provided to the user.
