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.
