DISPOSITIF D'AMPLIFICATION OPTIQUE POUR RESEAU OPTIQUE A CONTROLE DE GAIN AUTOMATIQUE

摘要

The optical amplifier (1) management process has a variable optical attenuator (4) and a first internal optical amplifier (3). The process measures the input power (Pin1) and controls the gain of the first power amplifier. The optical attenuation between the optical amplifier mechanism and a second forward amplifier is determined and the optical attenuation value held to maintain a constant attenuation value between amplifiers.
