SDH微波在传输网应用中的探讨

Discussion about SDH microwave application in transmission network

随着通信技术日新月异,SDH微波和SDH光缆设备日趋成熟,利用光纤、微波二者有机结合,通过合理地选择微波路由,并充分利用光和微波设备各自的性能特点来进行网络设计,进一步完善通信网结构,使网络生存性更强。文章根据光纤、微波混合组网方式(光纤与微波的互联、电路的互通保护、网管实现、网络同步、网络生存性),对城域网中集中型SDH微波的应用以及无源技术做了一些探讨。

With the communication technology developing rapidly, SDH microwave and SDH over optical-fiber cable are becoming more and more mature. If we use the optical fiber and microwave organically, select the microwave route reasonably, and design the network by making use of each trait of the optical fiber and microwave, the communication network structure will be more perfect and the network viability will be stronger. The paper discusses the mixed network of optical fiber ＆ microwave （ including interconnection between optical fiber ＆ microwave, circuit protection, network management realization, network synchronization, network viability, etc. ）, introduces the applications of the centralized SDH microwave in metropolitan area network and the passive technology.
