Abstract
PURPOSE:To constitute an inexpensive optical communication system by using an optical cable to transmit a main signal as a transmission path for a monitoring system. CONSTITUTION:The titled system is equipped with a fault information delivery means which allocates identification codes to identify repeaters B'' and C'' on the repeaters and also, inserts and delivers fault information from the device in the main signal and adds and deIivers the identification code, and a fault detecting means to detect the interruption of signal input and a transmission error. And the titled system is constituted in such a way that each of the repeaters B'' and C'' detects the interruption of the signal input or the transmission error from a preceding position side in its inside and delivers an allocated identification code and the fault information to a succeeding position side after inserting them in the main signal, and a faulty position is detected by diagnosing the information at a system monitoring device E' which monitors the system via terminal stations A'' and D''. In such a way, it is possible to constitute the inexpensive optical communication system.
