【摘要】 对于高速长途DWDM传输,色散管理技术被认为是最有潜力的解决方案,正成为人们关注的焦点。本文从色散、非线性和损耗三个方面简单介绍了当前系统需求,在此基础上重点列举说明了三种色散管理光纤线路:SMF+DCF、SMF+RDF和DMF,并对这三种色散管理光纤线路进行比较,最后得出结论DMF综合性能更好,更适合长距离,高比特率WDM传输。更多还原

【Abstract】 Dispersion Management technology is considered as the most potential solution for highbit rate and ultra long haul DWDM systems, and is being the focus of people’s attention. This paperintroduces the requirements of transmission system recently, according to which we mainly analyzethree type of dispersion managed fibers line: SMF+DCF、SMF+RDF and DMF. With comparison wecan conclude that DMF is most suitable for long-haul high-bit-rate WDM transmission.更多还原
