基于10G的E/GPON融合的研究

Research on E/GPON fusion based on 10G

随着新业务的不断出现,用户对带宽以及网络性能的要求也越来越高。随着光纤技术的发展,10G PON接入成了主流的接入技术,文章介绍了PON结构,由OLT、ONU、和ODN三部分组成,并介绍了每个组成部分的功能,简述了EPON和GPON技术的特点及协议的不同,提出了10G E/GPON融合的意义,最后设想了融合的研究方案。

With the continuous emergence of the new businesses, users＇ requirements for bandwidth and network performance are also getting higher and higher. With the development of optical fiber technology, 10 G PON access has become the main access technology. This paper introduces the PON architecture which consists of three parts： OLT, ONU and ODN. The functions of each part are also discussed. The paper describes the characteristics of EPON and GPON and the different protocols, expounds the significance of10 G E/GPON fusion and puts forward the fusion research plans.
