摘要
以太网无源光网络(EPON)是一种新型的光纤接入技术,它采用点到多点的网络拓扑结构、无源光纤传输。探讨了在实际中根据各种应用场景的不同,系统中的光网络单元(ONU)可以分为单住户单元(SFU)、家庭网关单元(HGU)、单商户单元(SBU)、多住户单元(MDU)和多商户单元(MTU)。指出不同类型的ONU所面向的用户是不同的,所支持的端口类型、端口数目和功能也各不相同。
EPON is a new fiber access technology, it utilizes P2MP(Point to Multi-point) network topology ar- chitecture and passive optical fiber transmission. Discussing that according to the difference of various scenar- ios, the ONU can be divided into SFU(Single Family Unit), HGU(Home Gateway Unit), SBU(Single Business Unit),MDU(Multi-Dwelling Unit) and MTU(Multi-Tenant Unit) in EPON system. Pointing out that for all kinds of ONUs, it is different for facing to client and supporting type and quantity and function of ports.
