LIU Xiu min, YANG Bo jun, ZHANG Xiao guang. Influence of polarization mode dispersion on NRZ and RZ System[J]. 2001,(2):39-42. DOI: 10.13756/j.gtxyj.2001.02.011.
The coupled nonlinear Schrodinger equation in birefringent fibers is solved by means of stepwise Fourier transform
and the influence of polarization mode dispersion(PMD) on NRZ and RZ system is numerically calculated. It is found that the influence of polarization mode dispersion on communication system can be effectively reduced by using RZ having certain pulse width. The optimum pulse width for maximum transmission distance is estimated.
