摘　　要：基于前馈控制结构,采用速率方程的"离散"算法,分析了双包层Er3+/Yb3+光纤放大器级联链路的功率漂移及钳制效果。Based on discrete algorithm of the rate-equation, analysis of power transient for cascaded an Er^3＋/Yb^3＋ co-doped double-clad fiber amplifier （EYDFA） chain is presented. The changes of power excursion with the number of EYDFAs, as well as results of gain control at pump control method were investigated.
