OPTICAL REPEATER OF OPTICAL SUBMARINE CABLE SYSTEM AND OPTICAL SUBMARINE CABLE SYSTEM EQUIPPED WITH THAT OPTICAL REPEATER

摘要

An optical repeater in which the possibility of entirely interrupting communication is low even when a feeding current decreases, and an optical submarine cable system in which the possibility of entirely interrupting communication is low because that optical repeater is provided. An optical repeater in which communication is prevented from being disrupted partially or entirely even when a feeding current decreases by stopping power supply to a part of a plurality of optical amplifiers provided in the optical repeater and/or to a part of a plurality of pump lasers provided in the optical amplifier, and an optical submarine cable system equipped with that optical repeater are achieved.
