摘要
光接入是宽带接入的发展方向,无源光网络(PON)是实现光纤到户(FTTH)的首选方案。本文首先分析了城域网概念的引入对接入网发展的影响和PON接入网的原理特点,指出PON拓扑结构完全符合城域网边缘的业务汇聚和接入模式,符合城域网概念引入后的用户业务引入段和接入层的结构特点,最后给出了PON技术与MSTP(多业务传送平台)结合构建多业务城域网的策略和PON技术在移动网络中的应用定位。
Broadband access network is developing toward optical access aspect, PON is the principal solution for FTTH. In this paper we focus on the effect on access network by introducing metropolitan network, analyzed the principle and characterization of PON. It＇s show that the diverse topology architecture of PON accord with services access mode in metropolitan access layer. Finally we summarized the strategies of building multi-services metropolitan network by combining MSTP and PON technologies, and application issues of PON in mobile networks.
