A conventional device of this kind operates by constantly supplying power supply current from a power supply device 3 to a branch/add amplifier 2 built into a branch repeater 1 via a power supply line 4, as shown in FIG. Since the main communication path 5 is branched and relayed, even if the signal transmitter/receiver 7 is not connected to the branch/add amplifier 2 built into the branch repeater 1 via the branch communication path 6, the branch/receiver 7 can be branched. The insertion amplifier 2 has the drawback of becoming a load on the main communication path 5 and consuming power supply current.

In order to operate this, it is necessary to insert branch repeaters 1 in all the planned installation locations of the signal transmitting/receiving device 7, including in the future, and to use a route that connects the entire device at the furthest distance using the relay connector 8. A main communication path 5 is provided, and the relay output of the branch repeater 1 inserted at the farthest end is connected to the signal shorting line 10 using the termination connector 9.
The branch repeater 1 is connected to a built-in terminator 11 to terminate the main communication path 5. When connecting the signal transmitting/receiving device 7 in the branch direction of the branch repeater 1, use the branch connector 12.
The main communication path 5 and the built-in branch/add amplifier 2 in the branch repeater 1 are connected using the signal shorting line 10, and at the same time, the branch communication path 6 and the signal between the branch repeater 1 and the signal transmitting/receiving device 7 are connected. The power supply line 4 from the transmitting/receiving device 7 to the branch repeater 2 is connected.

Because of this configuration, unless a signal transmitting/receiving device is connected in the branching direction of the branch repeater, the branch/add amplifier in the branch repeater is independent of the main communication path and will not affect the main communication path. No branch repeater is obtained.

As explained above, in the branch repeater according to the present invention, unless the branch/add amplifier installed therein is connected to a signal transmitting/receiving device in the branching direction,
Since it does not consume power, there is no need to waste power, and the current to the branch/add amplifier of the branch repeater is supplied from the signal transmitting/receiving device connected in the branch direction, so there is no need to provide any other special power supply. , the total power consumption of the branch/add amplifier of the branch repeater inserted into the main communication path is not a limitation, and the main communication path can be installed with high variability in consideration of future additions of signal transmitting/receiving devices, etc.; Further, by removing the branching connector of the branching repeater, the main communication path and the branch/add amplifier can be completely separated, so there are advantages such as ease of troubleshooting between the main communication path and the branching communication path.
