摘要

在5G前传网络中

单纤双向是重要的特征之一

相比4G和光纤接入（FTTx）网络中的单纤双向

5G前传网络中的单纤双向更为复杂。文章分析了在5G前传网络中实现单纤双向的情况及实现单纤双向关键光器件的原理

并分析了单纤双向系统的串扰源问题。分析结果表明

基于单只密集波分复用（DWDM）器件的DWDM单纤双向方案比基于光环行形器的DWDM单纤双向方案更有优势。

Abstract

In 5 G forward network

single fiber bidirectional technology is one of the important characteristics. Compared with single-fiber bidirectional technology in 4 G and Fiber To The X（FTTx） networks

single-fiber bidirectional technology in 5 G forward network is more complex. In this paper

several schemes to realize single-fiber bidirectional transmission in 5 G forward network are first introduced. Then the key optical devices to realize single-fiber bidirectional transmission and the crosstalk problem of single-fiber bidirectional system are analyzed. The comparison result shows that the single-fiber bidirectional scheme based on a single Dense Wavelength Division Multiplexing（DWDM） device has more advantages than the single-fiber bidirectional scheme based on an optical ring device.
