随着宽带业务的飞速发展,FTTx作为新型宽带业务逐步被大家所重视和期待。FTTx的主要网络技术是以太无源光网(EPON)。它将以太网技术与无源光网络(PON)技术结合起来,其目标是用最简单的方式实现一个点到多点拓扑结构的千兆以太网光纤接入网络。本文提出合理选择EPON的组网方式,对节省EPON的建设成本和运维成本,方便EPON网络的管理和维护起着关键性的作用。
With the rapid development of broadband services, FTTx as the new broadband services gradually by everyone attention and look forward to. FTTx’s main networking technology is Ethernet Passive Optical Network (EPON). It combines Ethernet technology with Passive Optical Network (PON) technology and aims to provide Gigabit Ethernet optical access networks with a point-to-multipoint topology in the simplest way. This paper presents a reasonable choice of EPON networking, EPON savings in the construction cost and operation and maintenance costs, to facilitate EPON network management and maintenance plays a key role.
