摘要

抖动是影响光通信质量的重要因素。文章首先简单介绍了光传送网（OTN）中的4种光数据单元（ODUk）时钟

然后介绍了ITU-T建议对这4种ODUk时钟的输出抖动、抖动容限以及抖动传递函数的规定

并具体分析了去映射器时钟ODCP的抖动

最后给出了一种异步去映射的实例以及抖动测量结果。

Abstract

Jitter is an important factor that can affect the quality of optical communication.In this article

four kinds of ODUk clocks in Optical Transport Networks（OTN） are first briefly introduced.Then

the requirements for their output jitters

jitter tolerances and jitter transfer functions specified in ITU-T recommendations are presented and the jitter of demapper clock（ODCp） analyzed.Finally

an example of the asynchronous demapper and the jitter measurement results are given.
