摘要

文章通过仿真得到了非归零（NRZ）码、载波归零（CSRZ）码、NRZ-差分相移键控（DPSK）和CSRZ-DPSK信号在偏振模色散（PMD）补偿前后的偏振度（DOP）值和剩余差分群时延（DGD）值。结果表明

与二进制强度调制（OOK）格式相比

DPSK补偿后的DOP值更多地分布在接近1的范围

剩余DGD值也较小

其中CSRZ-DPSK补偿效果最好

是实现PMD缓解与补偿动态结合的首选调制格式。

Abstract

By simulation

we obtain the Degree Of Polarization（DOP） value and the residual Differential Group Delay（DGD） value before and after ther Polarization Mode Dispersion（PMD） compensation of Non-Return-to-Zero（NRZ） code

Carrier-Suppressed Return-to-Zero（CSRZ） code

NRZ-DPSK and CSRZ-DPSK signals.The results show that compared with the binary On-Off-Key（OOK） format

more DOP values after the DPSK compensation are distributed close to 1 and the residual DGD values are smaller.In addition

CSRZ-DPSK has the best effect of PMD compensation and is the preferred modulation format for the dynamic integration of PMD mitigation and compensation.
