摘要:

推导了准线性光传输系统中受信道内四波混频、信道内交叉相位调制等信道内非线性效应影响的非线性传输方程,搭建了可构成多种色散管理方案的仿真传输链路,对10Gb/s、40Gb/s、100Gb/s、160Gb/s等四种不同速率的准线性光传输系统的色散管理方案进行了数值分析,分析了幅度抖动与定时抖动的关系,幅度抖动与系统Q值的关系,以及脉冲初始功率与系统Q值的关系。首次得到了单信道准线性光传输系统的最优色散管理方案与系统传输速率相关,并且随着系统传输速率的增加,前色散补偿部分的比例应逐步减少、后色散补偿部分的比例应逐渐增加并可量化的结论。

Abstract:

A nonlinear effect equation describes Intra-channel Four-Wave Mixing and Intra-channel Cross Phase Modulation in quasi-linear optical transmission system is deduced first, then the simulation model set for this system is built. Based on this model set, the dispersion management schemes of the quasi-linear optical transmission systems with 10Gb/s、40Gb/s、100Gb/s and 160Gb/s data rates are analyzed. We analyze the relationships of the amplitude jitters and the timing jitters, that of the amplitude jitters and the related Q values, that of the pulse initial powers and the related Q values. At the first time as we know, we have the conclusion that the optimal dispersion management scheme is related to the system transmission data rate, and the ratio of the pre- dispersion component should be decreased while the post- dispersion component be increased with the increase of system data rate.

Key words: optical communication, quasi-linear, dispersion management, nonlinear effects, amplitude jitter, timing jitter
