摘　　要：文章提出一种新的数值计算分析法,运用该计算方法得到了密集波分复用(DWDM)系统在衰减、色散走离和受激拉曼散射(SRS)效应耦合条件下的输出信号功率的数值解。并使用MATLAB软件进行了数值模拟仿真,通过数值计算绘出了在短距离传输条件下,不同输入光功率以及不同信道数时SRS效应对光通信系统性能的影响图。In this paper, a novel analytical method for numerical calculations is presented, by which the numerical solution to the output signal power in DWDM optical communication systems on the coupling condition of attenuation, dispersion walk-off and Stimulated Raman Scattering （SRS） effects is obtained. Then numerical simulation is performed by using MATLAB. Finally, on the basis of numerical calculations, a diagram showing the SRS effects on the optical communication system performances in short-range transmissions on the condition of different output optical power and channel numbers is drawn.
