摘　　要：基于速率方程的"离散"算法,实现了对双包层Er3+/Yb3+共掺光纤放大器级联链路功率瞬态及控制效果的分析。研究了级联链路中功率漂移与级联放大器数量的关系以及反馈控制抑制增益瞬态的效果。结果表明:随着级联放大器数量的增多,线性区功率漂移的斜率明显增大,达到峰值的时间越来越短,且漂移功率峰值达到5.1dB;反馈控制能有效抑制放大链路的功率漂移,但随着级联放大器数量的增多,功率漂移的峰值会逐渐增大。Based on discrete algorithm of the rate-equation, analysis of power transient for cascaded an Er3＋/Yb3＋ co-doped dou- ble-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 feedback control method were investigated.The result shows that slope in the linear region increases with the num- ber of EYDFAs, the same happens with the overshoot peak, and the maximum power excursion reached almost 5.1 dB in this chain. The study also shows thant feedback control method can suppress power excursions effectively, but the peak of power excursions in- creases with numbers of dropped channels gradually.
