在线掺铒光纤放大器的增益和噪声分析

本文提出了掺饵光纤放大器（ＥＤＦＡ）增益的精确模型，并对ＥＤＦＡ的增益进行了计算，其结果与实验相当符合。并在此基础上，结合光子数的Ｍａｓｔｅｒ方程和Ｐｅｒｓｏｎｉｃｋ关于接收机的理论，详细地分析了当ＥＤＦＡ为前放、中断时，其增益与接收机的噪声以及灵敏度在一定误码率下的关系。

Analysis of Gain and Noise of in-Line EDFAs

An accurate model for the Er-doped fiber amplifier(EDFA) is presented. The model is used to achieve the gain of EDFA. The computer resultes are in very good agreement with experimental results. From these fundamentals,including the photon number, Master equation and Personick,theory of optical receiver,the artical analyzes the no.se and sensitivity of receiver using EDFAs.
