摘要

利用Optisystem仿真软件搭建了基于DQPSK（差分正交相移键控）编码的WDM（波分复用）单纤双向传输系统

实现系统传输扩容;同时提出采用分段色散补偿方法抑制色散对系统的影响

利用非均匀信道间隔设置和非均匀色散管理降低四波混频效应。结果表明:在传输距离为600km、单信道速率为40Gbit/s的8信道WDM系统中

单纤双向传输时系统的品质因子（Q值）比单纤单向传输系统最大提高了14.9dB;对系统进行色散和四波混频抑制后

系统Q值还可以提高11dB以上。

Abstract

This paper sets up a simulation model by using the Optisystem for a DQPSK modulation-based single-fiber bidirectional WDM transmission system for performing system capacity expansion

inhibiting the effects of dispersion on the system by step dispersion compensation and reducing the FWM effects by non-uniform channel interval setting and non-uniform dispersion management.The results indicate that when the transmission distance of an 8-channel 40Gbit/s WDM transmission system is 600 km

the Qfactor of a single-fiber bidirectional transmission is improved by 14.9dB to the maximum compared with a single-fiber unidirectional transmission system.Furthermore

when the dispersion and FWM effects are inhibited

the system Qfactor can be improved by over 11 dB.
