Abstract This paper introduces the present development status of F T TH(Fiber to the Home) scheme based on EPON(Ethernet Passive Optical Network) technology,its system structure and working principle;describes the settings of F T TH optical line terminal(OLT),optical distribution network(ODN) and optical network unit(ONU) as well as ODN networking design principles and equipment selection principles in engineering;and gives a specific system block diagrams for several common types of construction modes of villas,multi-storey residences and high-rise residences.
Key words Fiber to the home(FTTH) Ethernet passive optical network(EPON) Optical line terminal(OLT) Optical distribution network(ODN) Optical network unit(ONU) Optical branching device (OBD)
摘 要 介绍基于 EPON(以太网无源光网络)技术的 F T TH(光纤到户)方案的发展现状、系统架构及工作原理;阐述 F T TH 的光线路终端(OLT)、光分配网(ODN)、光网络单元(ONU)设置, ODN 组网设计原则和工程中设备的选取原则;针对别墅、多层住宅、高层住宅等几种常见的工程建设模式给出具体的系统框图。
