| 摘 要： | 对基于40 Gbit/s 归零码-差分相移键控(RZ-DPSK)的密集波分复用(DWDM)系统,为抑制包括自相位调制(SPM)和交叉相位调制(XPM)效应在内的克尔非线性引起的光脉冲相位抖动,提出了4种色散管理方案:前置、后置、中间和平衡补偿方案.分析了这4种补偿方案在抑制克尔非线性效应方面的优劣.通过选择合适的方案,可使RZ-DPSK系统在抑制SPM和XPM效应上平均有2 dB的性能提高.

| Abstract: | For the suppression of optical pulse phase jittering induced by Kerr nonlinear effects including SPM and XPM in the 40 Gbit/s RZ-DPSK-based DWDM system,four dispersion management schemes are presented,i.e.pre-compensation,post-compensation,intermediate compensation and balance compensation,and their advantages and disadvantages in terms of the suppression analyzed.On the basis of appropriate scheme selections,2 dB performance improvement in average is achieved in the suppression of SPM and XPM effects in RZ... |
