摘要

文章分析和研究了密集波分复用（DWDM）网络中由于快速上/下波长等过程引起的掺铒光纤放大器（EDFA）增益瞬态响应的问题

给出了一种基于数字信号处理器（DSP）的电路前馈加反馈快速数字控制方法。实验证明

此方法能够显著抑制由于快速上/下波长过程引起的功率/增益波动。

Abstract

This paper studies and analyzes the transient response of Erbium-Doped Fiber Amplifier（EDFA） to fast channel adding/dropping process in DWDM networks and offers a fast digital control scheme with the combination of electrical feedforward and feedback based on Digital Signal Processor（DSP）.The experimental result shows that this method can be used to significantly suppress the power/gain excursions caused by the said process.
