摘　　要：作为目前主流的光接入技术,EPON/GPON难以满足未来每户百兆级的带宽需求,PON演进至10G PON的需求愈发强烈。从业务发展和技术驱动2个方面详细分析了PON演进的必要性,提出了由PON升级为10G PON的演进方案和PON/10G PON两网共存方案,同时对不同10G PON技术、不同组网模式下的上下行总带宽进行了详细测算。最后对不同场景下10G PON的部署方案提出了建议。As the mainstream of optical access technology,EPON/GPON cannot meet future bandwidth requirements for hundreds of megabytes per user,the demand for the evolution from PON to 10 G PON is urgent. It analyzes the necessity of PON network evolution from business development and technology improvement. It also presents the upgrade transition scheme from PON to 10 G PON and the coexistence scheme for both networks. It derives the bandwidth of uplink and downlink in different 10 G PON technologies and in different networking modes in detail. Finally,it gives suggestions on the deployment scheme for different scenarios.
