以太无源光网络的系统设计

The System Design of EPON

EPON(Ethernet over Passive Optical Network,以太无源光网络)是一种新型的光纤接入网技术,它采用点到多点结构、无源光网络传输,在以太网之上提供多种业务。主要研究EPON网络系统的设计和实现,以及EPON的网络结构特点,通过逻辑分析与实证相结合的办法,论述了EPON网的设计过程,得出了不同接入需求下的设计方案。创新之处在于从用户带宽需求入手实现资源配置最优的效果。

EPON （Ethernet over Passive Optical Network） is one new solution for optical fiber access network. It has a point-to- multipoint architecture and provides muhi-service basing on Ethernet. This article focuses on the design, implementation and the structure of EPON. Through the method of logical analysis and empirical combination, it discusses the design process of EPON, and obtains a design scheme for different access requirement. The innovation is to realize the optimal allocation effect of resources with the user bandwidth demand.
