Abstract
A feeding system is provided for supplying a current to repeaters on a communication cable including a feed line for conducting a current to the repeaters. The feeding system includes a plurality of branching units provided on the communication cable and terminal stations each being connected through at least one of the repeaters to one of the branching units, and each of the terminal stations feeding a current through the feed line to the repeaters. In addition each of the plurality of branching units includes at least one switching circuit for switching to connect the at least one of the repeaters to the communication cable or to the ground, depending on the amount of current conducting through the feed line in the communication cable. Further, the current thresholds of the switching circuits in the plurality of branching units are preferably different from each other.
