GPON是一种面向NGN的接入技术,它具有速率高、传输距离长、效率高和可伸缩性强等关键优势。同时,GPON支持引入更高带宽的以太网新业务,并能低成本提供传统的语音服务。本文介绍了GPON的标准化进展,给出了GPON的体系结构,分析了GPON的特点与应用,并将GPON与EPON进行了详细对比。
GPON is an access technology for NGN with key advantages of high speed, long transmission distance, high efficiency and scalability. At the same time, GPON supports the introduction of higher bandwidth new Ethernet services and offers traditional voice services at low cost. This paper introduces the progress of standardization of GPON, gives the architecture of GPON, analyzes the features and applications of GPON, and compares GPON and EPON in detail.
