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
The high-order effect that can not be neglected in the ultrashort optical soliton pulse transmission system based on high-speed transmission is studied. The effect of random high-order perturbations on the soliton system is studied. The results show that the stochastic high-order effect causes the soliton arrival time to jitter, which reduces the capacity of the soliton transmission system. The variance of jitter of soliton arrival time caused by stochastic third-order dispersion is proportional to the third power of transmission length. Variations of soliton arrival time caused by third-order nonlinearity jitter variance is proportional to the square of the transmission length
