| 摘 要： | 基于分布放大光孤子通信系统中增益补偿损耗过程中存在不可忽略的随机效应，研究了随机增益对光孤子通信系统的影响。结果表明：随机增益引起孤子到达时间的抖动，其方差与传输距离的三次方成正比，从而降低了孤子传输系统的通信容量；利用滤波器可以较好地抑制随机增益对孤子系统的影响。

| Abstract: | Based on the fact that there are unnegligible stochastic effects in the compensation of gain for the loss in the soliton communication system, the influence is studied of stochastic gain on the soliton transmitting system. The results show that the stochastic gain leads to the arrival time jitters, the variation of which is proportional to the cube of the propagation distance, and reduces the capacity of the system. The influence can be suppressed well by filters. |
