摘　　要：提出了一种可应用于波分复用(WDM)系统的偏振摸色散(PMD)自适应补偿方案。该方案以偏振度(DOP)为反馈信号,采用局部邻域结构的人工鱼群算法(LNAFSA)为控制算法,对低于设定阈值的一个或多个信道同时进行PMD自适应补偿。补偿后各补偿信道的DOP均大于0.96,眼图张开度明显增大,系统性能得到了改善。An adptive Polarization Mode Dispersion（PMD） compensation scheme μsed in Wavelength Division Multiplexing（WDM） is proposed.According to the scheme,choosing DOP as feedback signal,one or several channels which are below the set threshold are carried out adptive PMD compensation based on Local Neighborhood Artifical Fish Swarm Algorithm（LNAFSA） as control algorithm at the same time.After compensation,the DOP value of every compensated channel is over 0.96,the opening of eye diagrams is increased obvioμsly,indicating that this compensation is effective for improving the performance of systems.
