摘　　要：偏振模色散(PMD)是影响高速光传输系统性能的关键因素之一,如何构建一个适合有效的偏振模色散补偿器极具挑战性。新型光偏振模补偿(PMC)系统利用DSP和CPLD平台实现逻辑控制单元。该系统中引入了高速控制模块,使得每个周期的补偿时间缩短了将近100μs。利用粒子群优化(PSO)算法,整个系统能够完成一阶和二阶的偏振模色散补偿。Polarization Mode Dispersion （PMD） has a great impact on the performance of the high-speed optical transmission communication systems and it is challenging to establish an efficient compensator. A novel scheme of an optical polarization mode compensation （PMC） system is proposed. The proposed PMD com- pensation system employs logical controlling unit based on DSP and CPLD platform and implements with some high-speed control components which shorten the compensation time to nearly 100 microseconds per loop. The particle swarm optimization （PSO） algorithm is utilized in the whole system which could complete the first-stage and second-stage PMD compensation.
