Passive optical network ( pon ) and active optical network ( aon ) are two kinds of technologies that can be used to construct the optical access network 当前用于实现光接入网的技术主要有两种:无源光网络技术pon和有源光网络技术aon 。
Recent years , intelligent optical networks as the result of network research , using standard specification through a separated control layer to utilize the resources of network with highly efficiency 智能光网络技术则是近年来的研究成果,通过一个独立的控制层面,使用标准的规范来高效地利用网络资源。
Taking account of these requirements , in this paper we propose passive optical network technology as the promising access network technology , which can provide broadband access and can smoothly evolve to the age of ftth because of its numerous advantages such as less cost , more customers and wide range support 考虑到这些需求,本文提出了无源光网络技术作为接入网的主要技术,由于它存在着众多的优点而使得它不仅可以提供宽带接入,而且可以平滑地过渡到光纤到户时代。
