ABSTRACT:
In a WDM network employing optical amplifiers, a method of detecting changes in the number of channels present in erbium doped fiber amplifiers (EDFA) that are caused by faults or system reconfigurations. In accordance with the technique of the present invention, the power of one signal channel and the power of the amplified spontaneous emission generated by the local EDFA's are monitored.
