青海电力SDH光纤通信设计中应注意的问题

Some Problems Need to Be Noticed in Design of SDH Fiber Optic Communication of Qinghai Electric Power

同步数字系列 (SDH)、准同步数字系列 (PDH)是数字通信领域的两个技术系列。随着通信传输技术的不断发展和推陈出新 ,PDH开始被SDH逐步代替 ,SDH是今后电力通信网的主要组成部分。文章根据SDH传输网技术特点 ,从SDH网络拓扑结构选择及网络保护、设计规范应用。衰减受限系统计算、色散受限计算、功率放大使用及中继距离的确定方面 ,对青海电力SDH光纤传输系统设计中应注意的问题进行论述和讨论 ,以便SDH光纤通信更好地在青海电力系统应用。

Synchronous digital series and quasi-synchronous digital series is two technological series in digital communication field.With the constantly development of the transmission technology of communication,quasi-synchronous digital seies is replaced progressively by synchronous digital series,syunchronous digital series is mian component.According to the foundation transmission net and technological characteristic,the paper discusses the problem that should be paid attention to in design of SDH fiber transmission systen of Qinghai electric power.
