摘要
本文介绍了用“相位分析技术”在高速SDH系统中验证图案相关抖动的方法,并可望成为下一版本 ITU-T O.172建议的正式文本。本文也给出了一些SDH图案相关抖动的背景知识。
This article described the “Phase analysis technique” used in evaluatingpattern depended jitter in high speed SDH system and this method would be adopted by nextversion ITU-T O.172 specification. It also gave a candid way to evaluate SDH instruments bycomparing the SDH instrument's test result with the standard result evaluated by “Phaseanalysis technique” For more easily understanding, the paper also gave some backgroundknowledge of pattern depended jitter in high speed SDH system at the very beginning.
