摘　　要：随着光网络的快速发展,系统的传输码率逐渐提升,传输技术也不断地发展和完善。光纤传输系统中的各种因素造成的影响程度也出现了很大的变化。针对偏振模色散(PMD)对高速光纤传输系统造成的损害,对目前光域和电域的PMD补偿技术进行详细的阐述。通过比较各种方案,指出高速光纤传输系统中PMD的光域补偿技术更适用,发展空间大,而且性能好。其中光纤光栅补偿技术应用广泛,对单信道和多信道传输系统都适用。因此,光纤光栅技术最具发展潜力。With the rapid development of optical network,the transmission code rate is gradually improved,various kinds of transmission technology are continuously developed and perfected,and the influence resulted from various factors in optical fiber transmission system exhibits great changes.For the damages produced by the polarization-mode dispersion（PMD） on the high-speed optical fiber transmission system,this paper describes in detail the PMD compensation technology in current light field and electric field.The comparison of all options indicates that the PMD light-domain compensation technology,for its larger development space and better performance,is more applicable.The optical FBG（Fiber Bragg Grating） compensation technology is the widely-used and most potential technology,and quite applicable for both single channel and multichannel transmission systems.
