摘　　要：通过对非线性薛定谔方程的处理,推导了准线性系统中的相互作用方程,研究了强色散补偿光通信系统中的自相位调制、信道内交叉相位调制和信道内四波混频等非线性效应,分析了这些非线性效应所致脉冲对称扰动、定时抖动和振幅抖动的规律,并通过仿真实现了强色散控制系统中的稳定传输。Self-phase modulation (SPM), intrachannel cross-phase modulation (IXPM) and intrachannel four-wave mixing (IFWM) in dispersion compensated high speed optical communication systems are researched, and the role of the symmetrical perturbation induced by SPM, timing jitter induced by IXPM and amplitude jitter and ghost pulse induced by IFWM are analyzed. The stable transmission of 1600 km is verified in dispersion managed quasi-linear systems by simulations.
