摘要/Abstract

摘要： 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.

Abstract: Transmission properties of soliton system influenced jointly by stochastic variation of fiber parameters, ASE noise of amplifiers and interaction between neighboring solitons are considered in this paper. It is shown that stochastic variation of fiber parameters can change only the amplitude and energy of solitons when it exists alone in system and the arrival time jitter can be denied. However, when it exists with ASE noise and interaction, arrival time jitter of soliton becomes serious. It is proven that the jitter can be suppressed by filters.

Key words: stochastic parameters, arrival time jitter, soliton interaction
