Abstract
Aiming at the high stability requirements for light amplification in optical packet and circuit (OPCI) nodes,two main schemes of electrical and optical control for Er3+-doped fiber amplifier (EDFA) gain control were clarified.The principle of electrical automatic gain control was put forward with/without fine tuning of EDFA.The recent study progress of EDFA gain control was summarized.The specific control process of each control scheme was analyzed.The stage achievements by using these control schemes were shown.
