Remote control system of an optical repeater

摘要: In an optical digital communication system having a plurality of repeaters inserted in fiber cable, and pair terminal stations installed at the extreme ends designation particular repeater from station is performed by remote control signal which has pulse pattern with period designated to each repeater. Each may have switches for switching lasers improving operational reliability same redundant technique, and/or switch also said selecting repetition numbers pattern. Since times period, sequence periods are utilized designating repeater, large number objects (repeaters switches) can be controlled, (designation) very high.
