Hereinafter, the active patch panel according to the present invention and the integrated data wiring board system using the same will be described in detail with reference to the attached drawings.

Figure 4 is a configuration diagram of an active patch panel according to the present invention, and Figure 5 shows the front and rear sides of the active patch panel according to the present invention. The active patch panel according to the present invention includes an input unit 10 and an output unit ( 20), a cross-matrix switch unit 30, a control unit 40, and a power unit 50.

As shown in FIG. 5(a), the input unit 10 is a component that receives optical or electrical signals by providing an optical terminal 11, an electrical terminal 13 such as RJ-45, or an SFP terminal. When an SFP terminal is provided, an optical SFP module or a copper SFP module can be inserted into the SFP terminal and used as if an optical terminal 11 or an electrical terminal 13 is provided.

As shown in FIG. 5(b), the output unit 20 is provided with an optical terminal 21, a 110 terminal 23, or an SFP terminal and is a component that transmits optical or electrical signals to an in-house outlet. When an SFP terminal is provided in the output unit, the method of use is the same as in the case of the input unit 10. The 110 terminal 23 refers to the output terminal portion of the conventional 110 block 6. As shown in FIG. 6, the wire of the UTP cable is inserted into the 110 terminal 23 to form a line to the in-house outlet.

The cross-matrix switch unit 30 is a component that physically transmits optical or electrical signals transmitted from specific terminals 11 and 13 of the input unit 10 to specific terminals 21 and 23 of the output unit 20. , It is composed of a cross-matrix circuit 31 and a control circuit 33, as shown in Figure 7. Figure 8 illustrates a structure in which the cross-matrix switch unit is connected when both the input and output are optical signals, and Figure 9 illustrates a structure in which the cross-matrix switch unit is connected when both the input and output are electrical signals.

When the cross-matrix switch unit 30 receives an optical signal from the optical terminal 11 of the input unit 10, a photoelectric conversion circuit 35 for converting the optical signal into a digital electrical signal must be included, and the When receiving an analog electrical signal from the electrical terminal 13, a PHY (Physical interface transceiver) circuit 37 must be included to convert the analog electrical signal into a digital electrical signal. This conversion circuit is also provided in the same way for the output unit 20. That is, if the output unit 20 is an optical terminal 21, the photoelectric conversion circuit 35 must be included, and if the output unit 20 is a 110 terminal 23, the PHY circuit 37 must be included, and the input unit 10 or output unit If (20) includes an SFP terminal, a photoelectric conversion circuit 35 and a PHY circuit 37 must be provided on both the input unit 10 and output unit 20 sides.

8 and 9, the cross-matrix switch unit 30 is connected to the input unit 10 and the output unit 20 via the photoelectric conversion circuit 35 and the PHY circuit 37, and transmits signals through the control unit 40. It can be seen that the physical connection of is controlled. For reference, Figures 8 and 9 illustrate the case where the input and output are the same optical signal or Ethernet electrical signal. However, even when the input is an optical signal and the output is an Ethernet electrical signal, or the input is an Ethernet electrical signal and the output is an optical signal, the present invention is established.

The cross-matrix circuit 31 physically connects an input-side digital electrical signal to a specific output-side digital electrical signal, and may be implemented with a field-programmable gate array (FPGA) or an application-specific integrated circuit (ASIC). Figure 10 is a conceptual diagram showing the principle of operation of the cross-matrix circuit. When the cross-matrix circuit 31 is in the form of an N × N matrix with N inputs and N outputs, each digital electrical signal from the input side is transmitted to all N output sides. After demultiplexing is performed, only the digital electrical signals that require connection are multiplexed on the output side so that the digital electrical signals of specific input terminals (11, 13) are electrically connected to and transmitted to specific output terminals (21, 23).

The reason for emphasizing the electrical connection of digital electrical signals in the present invention is security. There are also software methods such as port routing or VLAN as a means of transmitting input signals to the output side, but these methods carry the risk of hacking because they share the network. Voyeurism using apartment wall pads, which has recently become a social problem, can be said to be a representative example of hacking damage that can occur when a network is shared. As previously mentioned in the technology behind the invention, the integrated data wiring board system according to the present invention is mainly used in high-end, expensive buildings such as high-speed information and communication buildings, and the level of security required by individuals and companies is very high, so the present invention Physical connection of signals such as is a realistic and feasible means of solving problems.

Previously, demultiplexing and multiplexing were performed sequentially from the input side to the output side, and it was explained as communication in the direction from the main distribution board to the in-house outlet. In the reverse direction, communication in the direction from the in-house outlet to the main distribution board was also described as demultiplexing and multiplexing in the same way. They are executed sequentially and signals are transmitted in the reverse direction. That is, in the case of reverse transmission, the output unit 20 becomes the input side, and the input unit 10 becomes the output side.

The control circuit 33 transmits a command to output the specific input terminals 11 and 13 of the input unit 10 transmitted from the control unit 40 to the specific output terminals 21 and 23 of the output unit 20 through a cross matrix circuit ( It is a component that converts electrical signal commands that drive 31).

The control unit 40 connects the specific terminals 11 and 13 of the input unit 10 and the specific terminals 21 and 23 of the output unit 20 from the network management device (NMS) of the integrated data wiring board system according to the present invention. It is a component that performs the command through the control circuit 33 when it is received. In addition, the control unit 40 creates a line number indicating the state of the line in which a specific terminal of the input unit 10 and a specific terminal of the output unit 20 are connected, and activates or deactivates each terminal of the input unit 10 and the output unit 20. Terminal setting to state (terminals at risk of physical hacking can be disabled), storage (backup) of specific line states, measurement of the size (level) of optical or electrical signals being input and output, active patch according to the present invention When an abnormality or error occurs in the panel, various functions such as alarming the network management device, controlling the power unit 50, and feeding power from the power unit 50 to the electrical terminal 13 or the 110 terminal 23 (PoE; Power over ethernet) are performed. Perform control activities.

The power unit 50 is a component that supplies power to the input unit 10, the output unit 20, the cross-matrix switch unit 30, and the control unit 40.

When the output unit 20 has 110 terminals 23, a test terminal 25 and a selection switch 27 may be further provided as shown in FIG. 11. In the present invention, the connection between the specific terminal of the input unit 10 and the specific terminal of the output unit 20 is performed in the cross-matrix switch unit 30, so even if the connection is incorrect, the correct connection is made by switching the cross-matrix circuit 31. This can be corrected. However, in the case of terminal 110 (23), if the UTP wire connected to the in-house outlet is connected incorrectly, it is very important to make the initial connection correctly because you need to find which wire is connected where and reconnect it. The test terminal 25 and the selection switch 27 are components provided for this initial wiring test.

The test terminal 25 may be formed of an RJ-45 terminal, etc., and is provided in 1:1 matching with the 110 terminal 23 of the output unit 20, and the wire of the test terminal 25 connects the selection switch 27. It is inserted into each slot (or hole) of the 110 terminal 23. Accordingly, the test terminal 25 is electrically connected to the in-house outlet, so the operator inserts the RJ-45 terminal of the test device into the test terminal 25 and operates the test device to check the connection status between the 110 terminal 23 and the in-house outlet. You can determine whether is normal or, if abnormal, which wire is connected incorrectly, and correct the wiring condition at the beginning.

The selection switch 27 is a switching element that connects the wire of the test terminal 25 to each slot of the 110 terminal 23 or separates it from each slot, and can select test or operation of the active patch panel according to the present invention. The reason why the selection switch 27 is necessary is because the test terminal 25 is not particularly used after being used at the beginning of construction of the integrated data wiring board system according to the present invention, so the test terminal 25 is separated from the 110 terminal 23. This is to do so. If the selection switch (27) is continuously connected to the 110 terminal (23), it is as if the selection switch (27), the 110 terminal (23), and the in-house outlet are bridged, and the electrical signal is transmitted from the 110 terminal (23) to the in-house outlet. This is not good, as noise is generated during normal operation.

The active patch panel according to the present invention has been described above, the core of which is to convert an input optical signal (or input analog electrical signal) into a digital electrical signal, connect it electrically to the desired output terminal through physical switching, and then convert the input optical signal (or input analog electrical signal) into a digital electrical signal. (or an output analog electrical signal), it can be seen that a specific output port of the optical switch or Ethernet switch of the integrated data wiring board system according to the present invention is connected to a specific in-house outlet.

Additionally, the network management device 130 may strengthen security by disabling unused ports of the main wiring board 100 and the intermediate wiring board 200 to prevent external intrusion or unspecified persons' intervention in operation management. That is, the optical ports of the first optical distribution box 120 of the main wiring board 100 and the second optical distribution box 210 of the intermediate wiring board 200 are remotely connected to the active patch according to the present invention through the network management device 130. By setting the panel's input/output terminals to enable or disable, it is possible to easily strengthen security and manage network resources.

The intermediate wiring board 200 is composed of a second optical distribution box 210, an optical switch 220, an Ethernet switch 230, and an active patch panel 240 according to the present invention.
