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