DWDM系统中色散走离条件下SRS效应的统计特性及仿真

Statistical Characteristics and Simulation of the Impact of SRS in DWDM Systems under the Condition of Dispersive Walk

文章在"时域分步法"存在衰减、色散限制和受激喇曼散射(SRS)效应作用条件下的N信道SRS效应计算模型基础之上,分别从理论和数值上分析了SRS效应影响下信号输出功率的统计规律,并使用Matlab软件进行仿真,通过比较理论公式仿真与数值仿真的一致性,对于进一步研究SRS效应对系统造成的误码率以及衡量DWDM系统中SRS效应对通信质量的影响有着重要的意义。

Based on the N-channel calculation model under the conditions of decay,dispersive walk and Stimulated Raman Scattering（SRS）coupling,statistical characteristics of the output power were analyzed theoretically and numerically.And analog simulations were carried out with Matlab software and the consistency of the theoretical and numerical values was compared,which is significant for studying the impacts of SRS on the miscode and capability of DWDM system.
