摘　　要：研究了色散控制高速光孤子通信系统中的非线性效应 ,对比分析了分别采用集总放大和分布放大两种放大模式对系统非线性效应的影响 ,并通过数值模拟分析了在这两种情况下非线性效应导致的定时抖动和振幅抖动随传输距离而变化的规律 。Nonlinear effect in high speed dispersion managed optical soliton communication system is researched. First, the impact of lumped amplification and distributed amplification to system nonlinear effect are compared. Then the rule of timing jitter and amplitude fluctuation changed with transmission distance in these two situations is analyzed numerically. As a result, the advantage of distributed amplification to restrain nonlinear effect is proved.
