光传送网中负载抖动累积的分析

Payload jitter accumulation in optical transport networks

光传送网(OTN)中由于信号的复用与映射和3R再生器等技术的使用会产生抖动,而抖动会对网络的信号质量产生影响。文章分析了负载信号映射抖动以及经过多个站点后的抖动累积。首先结合实际应用建立分析模型,然后在时域上分析模型得出抖动累积分析式,最后通过仿真得出结果。

Signal multiplexing and mapping and the use of 3R regenerator and other technologies give rise to jitters in Optical Transport Networks （OTN）, which affect the quality of network signals. This thesis analyzes payload signal mapping jitters and jitter accumulation in signal transmission after multiple OTN islands. It first sets up an analytical model on the basis of practical applications, then obtains an analytical formula for the jitters accumulation in the time domain on the basis of analyzing the model and finally achieves the results by simulation.
