GPON和XG-PON在广电接入网中的应用

Application of GPON and XG-PON in Radio and Television Access Network

当前,中国广电正在努力提升自己在媒体领域和通信市场的竞争力。为支撑业务发展,广电接入网将逐步从多方案统一到光纤到户(Fibre To The Home,FTTH)无源光网络(Passive Optical Network,PON)的路线上。同时,在数据流量持续增长的趋势下,广电接入网的部署既要满足现在的客户需求,更要前瞻布局未来。吉比特无源光网络(Gigabit Passive Optical Network,GPON)和非对称10G GPON(10-Gigabit Passive Optical Network,XG-PON)技术基于带宽、覆盖范围、服务质量以及技术升级等优势,在广电接入网的发展中具备应用潜力。基于此,介绍、分析GPON和XG-PON技术,借鉴其他三个运营商的接入网部署经验,为广电接入网的发展提供一定参考。

At present,China Broadcasting and Television is trying to improve its competitiveness in the media field and communication market,in order to support business development,broadcasting and television access network will gradually unify from multi-program to Fibre To The Home(FTTH)Passive Optical Network(PON)route.At the same time,under the trend of continuous growth of data traffic,the deployment of radio and television access network must not only meet the current customer needs,but also look forward to the future layout.GPON and 10-Gigabit Passive Optical Network(XG-PON)technologies,based on the advantages of bandwidth,coverage,quality of service and technology upgrading,have application potential in the development of radio and television access networks.This paper introduces and analyzes GPON and XG-PON technologies,and draws on the experience of other three operators in the deployment of access networks to provide some reference for the development of radio and television access networks.
