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果。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.
In this paper, we present a nonlinear optical fiber communication system with linearly dense wavelength division multiplexing (DWDM). The establishment and solution of arbitrary signals is based on the propagation characteristics equation of the channel with self-phase modulation (SPM), cross-phase modulation (XPM) effect, group velocity dispersion (GVD), stimulated Raman scattering effect (SRS) Conditions, get more comprehensive theoretical results. Focusing on the N-channel stimulated Raman scattering and cross-phase modulation nonlinear effects on optical signals caused by crosstalk analysis. And points out the way to reduce this crosstalk. Some conclusions are consistent with the experimental and numerical results reported in other literatures.
