SRS效应在双向波分复用系统中的单向等效

The Uni-directional Equivalent of SRS Effect in Bi-directional Transmission WDM Systems

对在双向传输波分复用情况下系统中的受激喇曼散射（SRS）效应进行了研究。对在不含放大器以及包含级联EDFA等情况下受激喇曼散射对双向系统的影响进行了理论及模拟分析，通过对照单向系统的对应性能，发现双向系统中的SRS效应的端特性可以通过一个对应的单向系统进行等效，从而使我们可以以较少的工作量对双向系统进行细致、准确、简洁的分析。

The method of dealing with SRS effect in bi-directional amplified and transmission WDM (Wavelength Division Multiplexing) systems is studied in this paper. Analytical and numerical results are given to show the influence of SRS to systems with and without EDFAs. The result shows that terminal feature of SRS effects in an bidirectional system can be equivalent to a uni-directional system.
