摘要
DWDM技术是近年来光纤通信网络中的一个研究热点,如何在接入网中应用DWDM技术,从而大大增强接入网的带宽,是目前业内人士普遍关注的问题。本文介绍了基于DWDM技术全光接入网的结构,其Feeder网及C/D网常见的拓扑,以及基于DWDM全光接入网中常用的波长分配算法。
DWDM becomes hot in the filed of optical fiber communication in recent years.It attracts more and more attention that how to apply DWDM into access network so as to expand its bandwidth.The paper presents the architecture of DWDM-Based all optical access network,including the feeder network and C/D network.What is more,it investigates the wavelength assignment algorithm of DWDM-Based all optical access networks.
