SDH光纤传输系统的信道处理及接收定时特性

The Channel Processing and the Characteristic of Receiving Timing for SDH Fiber Optic Transmission Systems

本文从ＳＤＨ信号流的帧结构和ＳＤＨ光传输系统采用的简单扰码的线路码型出发，分析了系统对信道的要求，提出了对通道带宽、定时恢复、对信号图案抖动抑制等有关系统设备设计参数的计算方法。

Based on the frame structure of SDH bit stream and the line code pattern of simple scrampling adopted in the SDH optical transmission system, the channel requirements of the system have been analyzed and a calculation method of channel bandwidth, timingrecovery and pattern jitter suppression etc. has been proposed.
