色散控制WDM孤子通信系统中的定时抖动

Timing Jitter in Wavelength-division-multiplexed Dispersion-managed Soliton Communication Systems

采用拉格朗日变分法在同时考虑本信道放大自发辐射 (ASE)噪声、相邻信道信号对本信道信号和ASE噪声等多种因素影响的情况下 ,分析了色散控制孤子的传输演化特性 ,给出了准稳态色散控制孤子传输动力学方程和定时抖动解析表达 ,并给出了三种扰动因素影响程度的比较。

In this paper, the influences of multi-perturbations originating from amplifier spontaneous-emission (ASE) noise and cross-phase modulation (XPM) in wavelength-division-multiplexed (WDM) are simultaneously considered by using the variational method to analyze evolvement characteristics of dispersion-managed soliton transmission. Simple analytical expressions for dynamics equations of dispersion-managed soliton and timing jitter are obtained. At last, the degrees of effect to system for three perturbations are given.
