In addition, 1L and 2L should also be interpreted as indexes that can distinguish between large and small voltages, not necessarily double voltage values, and voltages 1L and -1L also do not mean opposite voltage values with different signs. The sign of should be interpreted as an index that can distinguish differences.

In addition, the test signal may be understood to be composed of a current in which a DC signal having a voltage of 1L[V] and a pulse signal changed to 1L[V] and -1L[V] are superpositioned. For example, the test current may be understood as a superimposed signal of a DC signal having a magnitude of 5 [V] and a pulse signal changing to 5 [V] and -5 [V].

In addition, it can be understood that a test signal for determining whether or not the network switch and the patch panel are connected and the connection position in the communication room is supplied through the communication apparatus, but is eventually provided as a plug through the patch panel in the communication room.

For convenience of explanation, it is assumed that the L[V] value that defines the size of the test current is 5[V].

9 shows a circuit diagram of a state in which the patch cord 300 plug of the present invention is separated from one modular jack of a network switch and a circuit diagram in a state of lighting indexing, and FIGS. 10 and 11 are the patch cord 300 of the present invention. A circuit diagram of a plug mounted to one modular jack of a network switch and a circuit diagram of a lighting indexing state is shown.

In addition, it is assumed that the patch cord 300 connecting the network switch 10 and the patch panel 20 in the communication room is connected to the patch panel 20 side.

As described above, the communication cable may be composed of 4 pairs, and the light source unit 121 and the resistance unit 123 provided in the plug of the present invention are connected in series between the two communication lines 210, respectively, The two light emitting elements constituting the light source unit 121 may be connected in parallel within the light source unit 121. The light source unit 121 and the resistance unit 123 may be mounted on a substrate. Each light emitting device constituting the light source unit 121 may be an LED device, and may be mounted so that the current direction as a light emitting condition is opposite.

In general, network equipment supporting high-speed communication, such as a network switch, is not a structure that is directly electrically connected, and may be configured in the form of a transformer (transformation circuit, 11a and 11b) for reasons such as circuit protection as shown in the circuit diagram of FIG. have. That is, each pair of communication lines may be connected to the inductor 11a.

First, when the plug of the present invention shown in FIG. 6 is disconnected from the modular jack 11 of the network switch 10 and the test button of the remote tester 70 is pressed, 10 [V] through communication lines 3 and 6 ] And 0 [V] is supplied with a test signal in the form of a pulse of 1 MHz to form a closed circuit through the light source unit 121 and the resistance unit 123 and communication lines 3 and 6, as shown in FIG. As described above, the first light-emitting device 121a whose current direction is matched as a light-emitting condition emit light. In this case, the second light-emitting device 121b does not emit light because the current direction as the light-emitting condition does not match.

Since the test current is a high frequency pulse signal, the first light-emitting device 121a emits and blinks, but it is difficult to distinguish with the naked eye, so it can be identified that the first light-emitting device 121a continuously emits light.

However, as shown in FIG. 7, when the plug of the present invention is mounted on the modular jack 11 of the network switch 10, the first light emitting device 121a and the second light emitting device 121b are connected together for the following reasons. Glow.

That is, when the plug of the present invention is mounted on the modular jack of the network switch 10, a test signal in the form of a pulse of 1 MHz which is changed to 10 [V] and 0 [V] is supplied through communication lines 3 and 6 likewise. .

As described with reference to FIG. 8, the test signal in the form of a pulse of 1 MHz, which is changed to 10 [V] and 0 [V], has a size of 5 [V] and 5 [V] and -5 [V]. It can be understood as a superimposed signal of the pulse signal being changed, and the 5[V] DC signal constituting the test signal acts as a resistance component because the inductor 11a of the modular jack of the network switch 10 has a very low impedance at a low frequency. Therefore, as shown in FIGS. 10 and 11, the light source unit 121 connected in series with the resistance unit 123 of the plug or the like does not affect lighting.

However, in the 1MHz pulse signal that is changed to 5[V] and -5[V] constituting the test signal, the inductor 11a of the modular jack of the network switch 10 has a very high impedance at a high frequency and acts as a resistance component. It does not flow through the inductor 11a of the modular jack, but flows through the light source unit 121 and the resistance unit 123 of the plug. The resistance unit may include a capacitor in addition to the resistance to make the flow of current more clear.

And, the 1MHz pulse signal changed to 5[V] and -5[V] is a signal in which the direction of the current is alternately changed, as in the alternating current. As shown in Figs. 8(a) and 8(b), the resistance unit and the As the direction of the current flowing through the light source unit 121 changes, a pulse signal of 5[V], which is a component of the 10[V] test signal, turns on the first light emitting device 121a, and the component of the 0[V] test signal A pulse signal of phosphorus -5 [V] alternately turns on the second light emitting device 121b.

That is, since the 5[V] and -5[V] pulse signals change the direction of the current to 1 MHz, they are not identified as being alternately lit by the naked eye, and at the same time, the first light emitting device 121a and the second light emitting device 121b ) Can be observed.

Therefore, the 1MHz pulse signal, which is changed to 5[V] and -5[V] constituting the test signal, is the first light emitting device 121a and the second light emitting device 121b disposed in opposite directions like an AC signal. Each can be turned on.

Here, the light source unit 121 includes a first light-emitting device 121a of a first color and a second light-emitting device 121b of a second color in one unit, and each light-emitting device has a first color and a first color. Although composed of two colors, when the first light-emitting device 121a of the first color and the second light-emitting device 121b of the second color each independently emit light, the light source unit 121 may have a first color or a second color. However, when the first light-emitting device 121a of the first color and the second light-emitting device 121b of the second color emit light together, the light source unit 121 has a first color and a second color of light. It may also be configured to shine with the combined third color.

The light source unit 121 is composed of one unit, and a first light-emitting device 121a of a first color and a second light-emitting device 121b of a second color are provided therein to provide a first light-emitting device of a first color. When 121a and the second light emitting device 121b of the second color emit light together, the first color and the second color may be configured to glow in a mixed third color.

In this way, the first light emitting device 121a is individually lit, or the first light emitting device 121a and the second light emitting device are lit so that the light source unit 121 according to the present invention shines in a first color or a third color as necessary. A method of lighting the elements 121b together is used.

Therefore, when the test device is mounted in the communication apparatus 30 and the test is carried out, the operator of the communication room, when the first light emitting device 121a and the second light emitting device 121b are simultaneously lit, the patch cord 300 in the communication room ) At the same time as confirming that there is no abnormality in the connection, the connection position of the corresponding communication device 30 and the network switch 10 can be intuitively recognized, and when the test is performed, the identification of the state separated from the network switch 10 When the first light-emitting element 121a of the light source unit 121 of the plug is turned on, it is confirmed that the connection to the network switch 10 is necessary, and the plug that glows in the separated state is connected to the modular jack of the designated network switch to connect the communication room. You can get the job done.

In this way, when the communication room connection is completed, the lighting of the plug is in a state in which the first light-emitting element 121a is turned on alone, and the first light-emitting element 121a and the second light-emitting element 121b are lit together. It can be immediately identified that it is changed to, and through this, the operator can simultaneously check the connection status and the connection location of the communication room.

The lighting indexing function by the communication cabling management system according to the present invention can be arranged as shown in the table below.

Whether or not the light source unit 121 is turned on when voltage is applied through the communication device The first light emitting device 121a Lit O Lit O Lit X Second light-emitting device 121b Lit X Lit O Lit X Identification item Unplug network switch Equipped with network switch plug No patch panel connection / other communication line error

The patch cord 300 connecting the patch panel 20 and the network switch 10 may have at least one plug of the present invention provided on at least one side, and the patch cord 300 is patched in order to use the lighting indexing function. It is assumed that there is no abnormality in the communication line connected to the panel 20 and to the patch panel 20. Therefore, when the test current is applied through the remote tester 70 constituting the communication cabling management system of the present invention, when the plug that lights up in the communication room is not found, the network switch 10 and the patch panel in the communication room It can be understood that the patch cord 300 for connecting the 20 is not connected to the patch panel 20 or that there is an abnormality in the communication line from the communication apparatus 30 to the patch panel 20 .

Accordingly, the patch cord 300 for communication according to the present invention can identify the bidirectional connection position of the patch cord 300 in the communication room by using the optical module 141 provided in the plug, and the light source provided in the plug By using the unit 121, information about the state of communication connection from the communication apparatus to the network switch, whether or not a plug is mounted on the network switch in the communication room, etc. can be grasped.
