| 摘 要： | 利用耦合非线性薛定谔方程,计算了考虑PMD和非线性效应情况下8×40 Gb/s波分复用光纤通信系统中的波形及频谱.与不考虑PMD结果的比较表明:由于PMD的影响使得波形变宽,频谱分裂,同时通过比较还发现PMD对各信道的影响是不同的,这将有利于开发WDM系统中PMD补偿系统.

| Abstract: | Based on the coupled nonlinear Schrodinger for eight different optical pulses in single mode fiber with PMD, the wave shapes and frequency spectra of eight channels are given .The influences of PMD on eight channels are analyzed in comparison with that of no PMD to show the signal pulses broadening and the frequency spectra splitting. The most important conclusion is that the influences of PMD on eight channels are different, which would be considered in development of a new PMD compensation method in WDM optical fiber communication system. |
