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。
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.
