摘要

根据级联 EDFA密集波分复用系统光信噪比和系统等效噪声指数表达式

分析了各种因素对系统输出端 OSNR的影响

并分析了导致信道间输出 OSNR产生差别的各种原因 .

Abstract

The authors analyzed the factors which affect the output OSNR （Optical Signal-to-Noise Ratio） according to the expressions of OSNR and equivalent noise figure of DWDM system using cascade EDFAs.The reasons of difference in output OSNR between the channels were also discussed in this paper.
