摘　　要：随着WDM系统传输距离和光纤中光功率的增加,光纤的非线性效应对系统的影响及其优化成为研究关键。本文对海底光缆传输系统中非线性效应对系统的影响及其优化进行了分析。根据海底光缆系统的实际工作情况,模拟4×2.5Gbit/s系统进行了仿真分析,得出通过优化海底增益模块中掺铒光纤长度来选择最佳入纤功率,以改善系统性能,延长传输距离。Nonlinearity has become a key point as the transmission distance of WDM and the power in fiber are increasing.In this paper,the influences of nonlinearity on system and optimization was analyzed.And then the transmission system performances for the 4×2.5Gbps were simulated on the platform of OptSim according the practical going of undersea optical fibre cable.Simulationn showed that transmission distence can be prolonged and system performances will be improved through optimizing the length of EDF in remote module to select the best original power.
