摘要
自20世纪90年代DWDM系统商用以来,已迅速成为长途传输的主流方式。2000年以来,铁路以8横8纵为基础,相继建成了五大DWDM基础光传输网络环。如今伴随DWDM技术的广泛普及,传输网的维护与传统方式相比也有了较大区别。通过分析DWDM优势,以及铁路应用现状,结合相关文献和工作经验与大家讨论一下几种DWDM故障判断与定位的常用方法。
Since the 1990s, commercial DWDM systems has quickly become the mainstream of the long distance transmission way. Since 2000, at the foundation of the 8 horizontal 8 longitudinal railway system, the ministry of railways has successively built five DWDM foundational optical transmission network rings. Now with the widely development of DWDM technology, the transmission network maintenance also has more differences compared with the traditional way. The thesis analyse the advantege of DWDM , DWDM fault judging and the common positioning method combining with the application status of railway .
