The terminal exposed portion 116 may be configured in the form of a concave opening formed on a side surface of the housing.

The reason that the terminal exposed portion 116 on which the patch cord test terminal 119 is mounted is configured in the form of a concave opening is to prevent terminal damage caused by the terminal protruding from the outer circumferential surface of the housing, and a tester test terminal 521 to be described later. This is to provide a positioning function when mounting.

In addition, in order to facilitate the mounting of the tester test terminal 521 to the terminal exposed portion 116 configured in the form of a concave opening, the communication cable is introduced along the rear side of the housing to the terminal exposed portion 116 . A guide groove 114 may be formed.

5 shows the connection state of the patch cord test terminal 119, the optical element 118, and the test wire 230 provided in the patch cord 300 for communication according to the present invention.

Optical modules 117a and 117b are provided between a pair of patch cord test terminals 119a-1, 119a-2 or 119b-1, 119b-2, respectively, provided in a pair of connector units 100a and 100b, respectively. and the pair of optical modules 117a and 117b of the pair of connector units 100a and 100b may be connected via a pair of test wires 230 .

And, as shown in FIG. 5 , a pair of patch cord test terminals 119a-1, 119a-2 or 119b-1, 119b-2 provided in any one connector unit 100 is an optical element 118. ) is connected to the optical module 117 including a separate wire, etc., but the terminal itself may be connected by an extended wire or the like, or may be included in the optical module.

Therefore, when the patch cord test terminals 119a and 119b of the pair of connector units 100a and 100b are connected with the test wire 230, the pair of connector units ( The optical element 118 and the pair of test wires 230 of 100a and 100b may constitute a closed circuit.

Here, in the optical device 118 as an embodiment, the first light emitting device 118x of the first color and the second light emitting device 118y of the second color are configured in parallel in opposite directions to each other, and the patch cord test terminal Either one of the light emitting devices may be turned on regardless of the direction of the DC power supplied through 119a and 119b, and the first light emitting device 118x of a first color and the second light emitting device of a second color The first light emitting device 118x and the second light emitting device 118y may be provided in one package, rather than being configured as a separate module 118y.

As another embodiment, the optical device 118 is configured to include one light emitting device to supply DC power in which the positive voltage and the negative voltage supplied through the patch cord test terminals 119a and 119b repeatedly cross or supply DC power or AC power. By supplying power, the light emitting device may be configured to repeatedly blink regardless of the polarity.

Power is supplied through a pair of patch cord test terminals 119a-1, 119a-2, or 119b-1, 119b-2 of any one connector unit 100 in a state in which a closed circuit as shown in FIG. 5 is configured. Then, the pair of optical elements 118 on the closed circuit emits light regardless of the direction of the supplied power. Therefore, a worker performing communication network maintenance in a communication room, etc., in order to determine the connection position of the patch cord 300 for a specific communication, the patch cord test terminal 119a of any one connector unit 100 of the patch cord 300 for communication. A tester capable of supplying power to -1, 119a-2, or 119b-1, 119b-2) may be connected to determine the position of the opposite connector unit 100 through the light of the optical element 118 .

In this case, when power is supplied through the patch cord test terminal 119 of one connector unit 100, the corresponding connector unit 100 and the optical element 118 of the opposite connector unit 100 are lit together to make one It is possible to easily identify the connection positions of both ends of the patch cord 300 for communication.

Furthermore, the optical element 118 is configured in parallel with the first light emitting element 118x of the first color and the second light emitting element 118y of the second color in opposite directions to each other, and the connector to the patch cord tester 500 Depending on the direction in which the unit 100 is mounted, the color of the optical element 118 may vary when test power is supplied.

Therefore, when two workers work simultaneously inside the communication room, the opposite connector unit is a method of determining the tester mounting direction (direction of the connector, etc.) of the connector unit 100 of the test target communication patch cord 300 by mutual agreement. It is possible to distinguish the patch cords 300 for communication by changing the emission color of (100).

That is, the first operator is the connector unit 100 of the patch cord 300 for communication under test so that the first light emitting device, for example, a green light emitting device, emits light from the optical device 118 on one side of the patch cord 300 for communication to be tested. ) is mounted on the person's tester, and the second operator uses the test target communication patch cord ( 300) by mounting the connector unit 100 on the tester and performing each test, the opposite side of the patch cord 300 for communication tested by each operator by identifying the opposite connector unit 100 that emits light in the color they are looking for A function to check the connection location may also be provided.

That is, the patch cord 300 for communication according to the present invention does not separate it from the network equipment or the patch panel, and in a state in which communication is connected normally, power is applied to the patch cord test terminal 119 provided in each patch cord 300 for communication. Through the lighting function, the connection position can be precisely specified and visually identified.

In this way, the patch cord 300 for communication according to the present invention can specify a bidirectional connection position without disconnecting the connector from a connection device such as a patch panel or network equipment, thereby minimizing inconvenience in the maintenance process.

In this way, the function of accurately specifying the connection location through the lighting function in the state in which the network communication system 1 is operating can be applied to the security field for preventing hacking. In optical communication systems, hacking of optical cables is attempted by removing the cable jacket from a specific area of the optical cable and bending the optical fiber to obtain data by receiving the optical signal leaking without total reflection at the bent part.

When the network equipment detects that the power of the received optical signal is low as much as the optical signal leaked due to tapping at a specific port when tapping occurs, the test power is applied to the connector unit of the patch cord connected to the corresponding port in the manner described above to apply the test power to the network. In the configuration, you can check which path is being hacked physically.

In the conventional network communication system, when a problem occurs on a specific path, in order to find the end of the path, it is necessary to check the number/tag to find it, and if there is no tag, the connection section cannot be easily checked. Code and patchcord testers can be used to easily identify hacking paths by specifying the location of connections via lighting features.

By applying the anti-hacking optical fiber in the patch cord of the present invention, it is possible to obtain the side effect of easily identifying the path through which the hacking attempt is made while blocking the hacking of the network communication system.
