摘要
随着用户对带宽需求的不断增加,光传输在接入网中的作用越来越重要。当前,最有前景的光接入网方案是无源光网络(PON)技术,而吉比特无源光网络(GPON)是PON技术中最具有代表性的。对基于GPON OLT网络部署思路和原则、OLT节点部署方案等关键问题进行了详细分析,并在此基础提出了两种OLT节点部署方案,同时对两种方案的优缺点进行了比较。
With the increasing demand of bandwidth by the user, optical transmission in the access net becomes more and more important. At present, the most promising optical access-net scheme is to adopt PON technology, while GPON technology is the most representative technology. This article gives detailed discussion and analysis on idea and princiPle of GPON OLT-based network deployment, including the critical OLT deployment scenario, and proposes two schemes of OLT bureau deployment. The comparison of these two schemes is also done in this paper.
