摘要
从理论上数值分析和比较了一阶和二阶偏振模色散对各种光调制码型(RZ、CSRZ、RZDPSK、CSRZ－DPSK)的偏振模色散的影响，结果表明：不同码型的偏振度大不相同，RZ码受偏振度影响最大，CSRZ－DPSK码受二阶偏振模色散的影响最小，在补偿系统中更适合缓解偏振模色散．
Abstract
In the polarization mode dispersion(PMD) compensation experiment,the degree of polarization (DOP) is used as the most common feedback signal,which reflects PMD and its influence on the transmission system factually. The influences of first-order and second-order PMD on DOP of four optical modulation formats(RZ,CSRZ,RZ-DPSK and CSRZ-DPSK) are compared and mathematically analyzed.The result shows that different formats have different DOP and the second-order PMD has less influence on DOP of CSRZ-DPSK format,which is fitter for mitigating PMD than the other formats in self-adaptive PMD compensation system.
