摘　　要：在DWDM系统中受激喇曼散射(SRS)效应是一种重要的非线性效应。将巩稼民的无色散条件下N信道的SRS效应模型和Singh_Hudiara模型分别加入色散走离,采用"时域分步法"对多信道、长距离传输中的"色散"以及SRS效应所带来的影响进行仿真。通过对这两种模型的功率转移仿真图对比,得出信号功率的变化随着信道波长的增加而线性增长的结论。这对SRS研究有着重要的意义。The SRS（Stimulated Raman Scattering） effect in DWDM systems（Dense Wavelength Division Multiplexing） is an important kind of nonlinear effect.In this paper,the N channels SRS effect model of Gong Jia-min under non-dispersion condition and Singh Hudiara model is added to dispersion walk-off respectively.The time domain step method is adopted to simulate dispersion caused by multiple-channels and long-distance transmission,and the influence of SRS effects.The conclusion that signal power grows in a linear manner with the increasing of channel wavelength is drawn from the comparison of power transfer simulation diagram for two models.It is of great importance to the further study on SRS.
