摘要

对光纤到户（FTTH）网络来说

一个低成本高效的灵活接入方案是非常重要的。在波分复用-无源光网络（WDM-PON）中

用户端的收发器件以及波长分配方案是系统的关键。单纤双向单波长方案可以大大简化网络结构

降低用户的接入成本

但这种结构存在很严重的瑞利反向散射的串扰。文章分析了各种不同ONU端光源的实现方式

并分析了若干种抑制瑞利反向散射串扰影响的技术。

Abstract

A cost-effective solution for flexible access is very important for FTTH network deployment.Transceivers at the user premises and wavelength distribution schemes are crucial for WDM-PON.Bidirectional single-fiber single-wavelength transmission schemes can considerably simplify the network structure and reduce the average access cost of each customer

but Rayleigh backscattering crosstalk has a serious effect on the system.This article analyzes various solutions for ONU light source and several solutions for suppressing Rayleigh backscattering effect.
