Abstract:This paper discusses the monitoring and controlling of EDFAs as boosters, online amplifiers and preamplifiers in the all optical relay fiber optic transmission system, puts forward a new solution for monitoring and controlling the gain and switching of in－service and spare online EDFAs by coherent OTDR and local control unit. The scheme can realize the monitoring of online EDFAs of downstream and upstream fiber optic line at a single end.
