Abstract :
We present a simple dynamic gain control of a booster amplifier (EDFA-erbium-doped fibre amplifier) with an optical supervisory channel power adjustment in WDM transmission systems. As a result, we performed gain clamping and power clamping of EDFA in the optical link. We can transmit 10 Gbps WDM signals and a 155 Mbps supervisory signal through a single mode fiber 320 km according to the change of signal channel number
