摘要
针对当前光分组与线路节点光放大高稳定性需求,依据电、光两种主流控制方案,阐明了掺Er3+光纤放大器(EDFA)带微调和无微调情况下,基于电的自动增益控制机理。综述了EDFA增益瞬态控制研究的最新进展。分析了各种增益控制方案的具体控制过程。呈现了这些控制方法所取得的阶段性成果。
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 Er^3 ＋-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.
