摘　　要：算力网络对运营商越来越重要,也是各运营商的网络发展趋势。接入网作为接入用户的最末端网络,提升接入网的带宽、速率等对算力网络非常重要。50G无源光纤网络(Passive Optical Network,PON)技术带宽是现有10 G PON的5倍。因此,研究50 G PON的技术也是下一代PON网络的趋势。主要介绍了背景、PON的发展趋势、下一代PON演进技术的总结和分析,同时也对缩短用户接入的光纤到房间(Fiber To The Room,FTTR)技术架构、关键技术、应用场景等进行了简单的总结分析。The computing network is becoming more and more important to the operators,and it is also the network development trend of the operators.As the terminal network of access users,it is very important to improve the bandwidth and speed of access network.The 50G PON technology has five times the bandwidth of the existing 10G PON.Therefore,the research of 50G PON technology is also the trend of Next Generation PON network.This paper mainly introduces the background,the development trend of PON,the next generation of Pon Evolution Technology Summary and analysis。At the same time,it also makes a simple summary and analysis of the Fiber To The Room(FTTR)technology architecture,key technologies and application scenarios to shorten the user access。
