摘    要:无源光网络是一种新兴的覆盖最后1km的宽带接入光纤技术。文章简要介绍了时分复用无源光网络(TDM—PON)技术,然后提出从TDM—PON到WDM—PON(波分复用无源光网络)过渡所可能经历的阶段并对这几个阶段进行论述。接下来着重介绍了WDM—PON的基本工作原理及作为一种宽带接入技术的优势,并对其关键技术,如多波长激光器、波长路由器等,作了一些分析和探讨。

关 键 词:无源光网络  时分复用无源光网络(WDM-PON)  波分复用  光纤接入网

Abstract:PON is a kind of covers last 1 km new broadband access technology.In this paper, the current TDM-PON technology has been presented first. Then the transitions, which might go through from TDM-PON stage to WDM-PON stage, were proposed and the situation of these stages was described in detail. As one kind of broadband access technologies, WDM-PON has many predominant advantages, and its basic operation principle is introduced in this paper. Finally some analysis and discussion to its key technology, for instance MWL,WGR etc, were done.
Keywords:PON  WDM-PON  fiber optical access network
