摘　　要：接入网从EPON/GPON向10G PON演进的过程中,面临局端和终端设备成熟度不同等问题,无法一步到位升级到10G PON,因此如何在技术和成本间取得平衡,实现向10G PON网络的平滑演进是当前宽带接入网面临的主要问题。基于现网向10G PON演进,从宽带提速、技术演进、部署策略等多个方面进行分析,针对EPON和GPON等不同技术以及新建、改造等不同场景,分别提出演进策略和方案,对网络建设具有积极的指导意义。As the access network evolves from EPON/GPON to 10G PON,facing the problems of different OLT and Optical modem maturity,it cannot be upgraded to 10G PON in one step.Therefore,how to balance technology and cost,and realize the smooth evolution to the 10G PON network is a major problem for the broadband access network.Based on the evolution of current network to 10G PON,it analyzes various aspects including broadband speedup,technology evolution and deployment strategy.The evolution strategies and schemes are proposed for different technologies,such as EPON and GPON,as well as different scenarios,such as newly built and reform,which are instructive to the network construction.
