Abstract

With the ever growing development in erbium-doped-fiber-amplifier (EDEA) repeatered wavelength-division-multiplex (WDM) systems, it is important to use a practical supervisory method that facilitates simultaneous monitoring and fault-locating capability. In this paper, an in-service supervisory EDFA-repeatered WDM transmission system, based on a recently WDM supervision technique1 and the use of strongly inverted EDFAs,2 is demonstrated for the first time to our knowledge. Simultaneous fiber-fault location and status monitoring and diversity protection of EDFA repeaters are achieved without degrading the 2.5 Gbit/s service in a five-EDFA 365-km four-channel WDM system.
