随机高阶效应对孤子传输系统的影响

基于高速传输的超短光孤子脉冲传输系统中存在不可忽略的高阶效应，研究了随机高阶效应的扰动对孤子系统的影响。结果表明：随机高阶效应引起孤子到达时间抖动而降低了孤子传输系统的容量，其中随机三阶色散引起的孤子到达时间抖动方差与传输长度的三次方成正比，随机非线性色散和随机随时间变化的三阶非线性引起的孤子到达时间抖动方差与传输长度的一次方成正比

Stochastic High Order Effects on Soliton Transmitting System

Based on the unneglected high order effects in an ultra short soliton transmitting system, studies of stochastic high order effects on the soliton transmitting system are performed. The results show that the stochastic high order effects lead to the arrival time jitters and reduce the capacity of the system. The arrival time jitters variance resulted from the stochastic third order dispersion is proportional to three powers of the transmitting distance, and that from the stochastic nonlinear dispersion the third order nonlinearity varying with time is proportional to the transmitting distance.
