摘要
当前光接入网的连接对象和覆盖场景不断拓展,光接入网的拓扑结构需要满足网络发展的新需求。本文研究探讨了光接入网的拓扑结构描述方式,提出了从光纤层面和光缆层面两个角度对光接入网的拓扑结构描述。在光纤层面,对现行国际标准规定的光接入网拓扑结构进行了调整;在光缆层面,对光接入网的主要拓扑单元进行了梳理归纳。两者相结合,可衔接光接入网承载的光系统和物理设施部署,更有效地对光接入网拓扑结构进行描述。
Nowadays the connection objects and coverage scenarios of the optical access network are expanding,and the topologies of the optical access networks should meet new requirements of the network development.This paper studies and discusses description of the topological structure for optical access network,and propose to describe optical access network topologies from both the optical fibre level and the optical cable level.At the optical fibre level,the optical access network topologies are given by adjusting topologies in existing international standard;At the optical cable level,main topological units are summarized.By combining the two levels,the optical system carried by the access network and physical facility deployment are connected,this will describe the topology of the optical access network more effectively.
