| 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 effe... |
