Abstract

A method of and system (11) for detecting and reporting faults in an all-optical communication system. The system monitors each of the optical fibers (19a-19n) and uses the optical supervisory channel system (31) to detect and report faults. Whenever the system detects a fault in any of optical fibers, the system forms a message identifying the fault and transmits the message in optical supervisory channel carried by at least one of the optical fibers.
