该文研究了光纤损耗、色散、非线性系数等参量无规变化，放大器自发辐射噪声（ＡＳＥ）和孤子间相互作用同时存在时孤子系统的传输特性．发现光纤参量随机变化仅引起孤子幅值和能量变化，孤子中心抖动可以忽略，而相互作用对孤子中心抖动有显著影响．相互作用和ＡＳＥ噪声并存时对孤子中心抖动的影响更为严重．文中证明，这些抖动因素均可用滤波器加以抑制． In this paper, the propagation characteristics of the soliton systems such as random loss of fiber loss, dispersion, nonlinear coefficient and so on, as well as the spontaneous emission noise (ASE) of the amplifier and the interaction between solitons are studied. It is found that random variation of optical fiber parameters only causes the amplitude and energy of the soliton to change. The jitter in the soliton center can be neglected. However, the interaction has a significant influence on the soliton jitter. The co-existence of ASE noise and interaction have a more serious effect on the soliton center jitter. The paper proves that these jitter factors can be suppressed by the filter.
