光纤接入发展展望

随着社会的进步和人们生活水平的提高,人们对带宽的需求也快速增长。以无源光网络（PON）技术为代表的光纤接入技术在全球获得了广泛的应用,在中国的发展最快,应用规模最大。但在发展过程中也遇到了诸如政策支持力度不够、高带宽应用缺乏、配套基础设施较落后、运维技术有待提升等困难。为了更好满足多业务承载对光接入网络带宽和服务质量（QoS）的需求,本文在对目前光纤接入现状分析的基础上,从技术标准、应用场景、产品形态、运维管理等4个方面对光纤接入的发展趋势进行了深入剖析,提出了下一代光纤接入的主要研究方向。

Prospect of Optical Access

Along with the progress of human society and the improvement of people＇s living standards,people＇s bandwidth demand is growing rapidly.Passive Optical Network（PON）,as a typical fiber access technology,has been widely used worldwide,especially in China However,it has encountered difficulties including lack of policy support,lack of killer applications,supporting infrastructure falling behind,operation,administration maintenance needing improvement.,In order to meet the higher bandwidth and better Quality of Service（QoS） requirements for multiple services,this paper provides an overview of current optical access network,and then addresses in detail the future development tends of optical access networks from four aspects including technical standards,application scenarios,product shape,operation and maintenance management,This paper also provides hot research topics of next generation optical access.
