摘要

采用单纤双向系统是实现光纤通信系统扩容的有效解决方案。文章提出了采用波长移位技术降低单纤双向传输系统中的反向瑞利散射的方案

并介绍了采用OptiSystem仿真软件搭建的基于QPSK（正交相移键控）调制方式的双向传输系统仿真模型。仿真结果表明:在最优发射功率为3dBm、传输距离为360km的情况下

双向传输系统比传统的单向传输系统Q值提高了1.5倍

误码率降低到10-170

同时

满足Q>6的最大传输距离可达1 600km。研究表明

单纤双向系统在传输容量相同的情况下

较之于传统单纤单向系统可以少用一根光纤

其传输性能也有所提升。

Abstract

Using a single-fiber bidirectional system is an effective solution to the capacity expansion of the fiber-optic communication system and the simulation study of its performances is important to its practical applications.This paper presents an effective scheme

i.e.using the wavelength shifting technology to lower the reverse Rayleigh scattering in the system and using OptiSystem to set up a simulation model for the QPSK modulation-based bidirectional transmission system.When the transmitting power is 3dBm and the transmission distance is 360km

the Q factor of the proposed system is improved by 1.5times and the BER is reduced to 10-170 as compared with the traditional unidirectional WDM system.In addition

when the Q factor is over 6

the maximum transmission distance can reach 1 600km.Research results show that when the transmission capacity is the same

the bidirectional system can reduce the use of one fiber and its transmission performance is also somewhat improved.
