Theoretical and simulation study of four-wave mixing noise in coherent 16-QAM DWDM system
摘要
Abstract
This paper uses Optisystem and Matlab co-simulation,presents a mixed model to calculate the standard deviation of four-wave mixing (FWM) noise standard deviation for 16-QAM DWDM system based on a nonlinear separation model.Under the condition of different transmission rate and multiplex channel numbers,the paper uses the model to analyse the effect of FWM noise on DWDM system and the overall nonlinear tolerance of the system.关键词
