本文研究了波分复用系统中光纤色散对受激喇曼散射串扰的影响，提出了在考虑信号调制几率特性和脉冲走离效应后，系统误码率和功率代价的理论计算方法，并对典型系统进行了数值模拟。研究结果表明，由光纤色散引起的信号脉冲走离可以降低受激喇曼散射串扰，尤其是在复用信道较多、信号传输速率较高的系统中，光纤色散的作用更加明显
In this paper, we study the influence of fiber dispersion on stimulated Raman scattering crosstalk in WDM systems, and propose a theoretical calculation method of system bit error rate and power cost after considering the signal modulation probability and pulse walk-off effect. The typical system is numerically simulated. The results show that the dispersion of signal pulses caused by fiber dispersion can reduce the stimulated Raman scattering crosstalk. Especially in the system with more multiplexed channels and higher signal transmission rate, the effect of fiber dispersion is more obvious
