普通单模光纤中光孤子传输问题的研究

Research on Optical Soliton Transmission in Common Single Module Optical Fiber System

在使用普通单模光纤的光孤子传输系统中，放大器自发辐射（ＡＳＥ）噪声和色散波逸出是限制光孤子传输的两个主要因素，它们将引起孤子能量抖动和定时抖动，从而导致系统误码．本文分别研究了带限光滤波器对ＡＳＥ噪声的抑制和非线性增益对色散波的抑制以及对孤子传输系统的稳定作用，并设计了使用普通单模光纤的光孤子传输系统．

In the optical soliton transmission systems using common single module optical fibers, the amplified spontaneous emission (ASE) noise and the overflow of dispersion waves are the two main factors that can cause energy and timing jitter of soliton, thus leading to some errors in bit rate of system. In this paper, we study the restraint of the ASE noise with band-limited light filter and the restraint of the dispersion wave with nonlinear gain and their stabilization to the optical soliton transmission systems. Based this the optical soliton transmission system using common single module fibers is designed.
