摘　　要：对于高速长途密集波分复用(DWDM)传输,必需采用各种各样的色散补偿、色散管理技术,其中,交替使用正负色散光纤构成色散管理线路(DML)是可行的解决方案之一,在国际上已经取得显著进展,正成为人们关注的焦点,国内在这方面的研究报道还少见。文章以高速长途DWDM系统对传输线路的性能要求为基础,综述了有代表性的3种不同类型的DML的特点和最新进展。All kinds of technologies for dispersion compensation/dispersion management have been applied in long-haul and high-rate DWDM transmission, in which, dispersion management line （DML） consisting of alternating fibers with positive and negative dispersion is considered as a feasible solution. DML develops quickly and attracts more and more attentions, but which is rarely reported in China. This paper, according to requirements of long-haul high-rate DWDM to transmission line, illuminated the characteristics and recent developments of three type of DML are illuminated.
