摘　　要：目前国内外运营商已开始规模建设40G WDM系统,为实现40G WDM系统的超长距传输,应对40G WDM系统的色散补偿做到最优配置。本文在实验室测试数据的基础上,研究出各种色散补偿模块的补偿效果,最后提出40G WDM系统现网应用时色散补偿的一些建议。The telecom operators home and abroad have begun to build 40G WDM system on large scale.In order to realize the extra-distance transmission of 40G WDM system the dispersion compensation of 40G WDM system should be allocated optimally.It studies the compensation performance of various dispersion compensation modules on the basis of the data gained from the test in the laboratory.Finally,it gives some suggestions for the application of dispersion compensation in the existing 40G WDM system
