DWDM系统的非线性效应和串扰分析

本文在线性密集波分复用（DWDM）的具有非线性效应的光纤通信系统中，建立和求解任意信号通过具有自相位调制（SPM）、交叉相位调（XPM）效应、群速色散（GVD）、受激拉曼散射效应（SRS）的信道时的传播特性方程，依据一定的系统条件，得到更加全面的理论结束。重点讨论了N信道受激拉曼散射和交叉相位调制非线性效应对光信号引起的串扰分析，并指出减小这种串扰的方法，有些结论与其他文献报导的实验分析结果和数值解结果相同。

Analyse of non-linear effect and evocatie interfer-ence in the DWDM system

In this paper the possess non-linear effect optical fiber communication system of the tinear dunsity wave di vi sion multiplexing (DWDM), Foundation and solve arbitrary signal pass take on stinn1ated Raman scattering effect(SRS)' channe1 of propagat ion characteristic equation, according as certain system condi tion, get much more com peahensive theoretical resurlt, it has been discussed that N channel stimulated Raman scattering and cross-phase modulation non-1inear effect for optical signal evocative interference of analyses, and point out reducing such i nterference of means, the experimental analysis the result with that numerical solution came to the same thing, the some conclusion with else literature report of outcome coincide
