SUBMARINE CABLE FEEDING SYSTEM

摘要

PROBLEM TO BE SOLVED: To deploy submarine repeaters in a matrix form by branching a feeder of a submarine cable.

SOLUTION: Constant voltage feeding sections 1 and 1a installed on a land or the like feed a constant voltage to a submarine feeding distributor 10 through a constant voltage feeder 2 or 2a. The submarine feeding distributor 10 converts the constant voltage feeding into negative constant current feeding and positive constant current feeding and applies constant current feeding to a submarine repeater 20 through a constant current feeder 3 or 3a or 3b. Further, the constant voltage feeding is applied to a submarine feeding distributor 10 or 10a connected to a next stage through the constant voltage feeder 2 or 2a. the submarine feeding distributor 10a converts the constant voltage feeding into negative constant current feeding and positive constant current feeding and applies constant current feeding to a submarine repeater 20 through a constant current feeder 3 or 3a or 3b. Moreover, the constant voltage feeding is applied to a submarine feeding distributor 10 or 10a of a plurality of stages through the constant voltage feeder 2 or 2a. The submarine repeater 20 converts a constant current fed from the submarine feeding distributor 10 or 10a or other submarine repeater 20 through the constant current feeder 3 or 3a or 3b into a constant voltage and feeds the voltage to an observation section 4.
