Polarization-mode Dispersion Compensation Technique for High-speed Optical Fiber Transmission System

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.
