Zhu Zhiying, Xu Ming, Luo Jun, et al. Study on RZ-DPSK dispersion management scheme for Kerr nonlinear effect suppression[J]. 2009,(5):10-13. DOI: 10.13756/j.gtxyj.2009.05.006.
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-DPSK systems.
