长距离PON接入技术研究

摘要

This paper puts forward the remote protocol conversion technology to realize long-reach passive optical network (LR-PON) based on the analysis of typical network structures. The feeder line adopts point-to-point transmission protocol and the distribution line uses PON protocol. The remote protocol converter (RPC) conversion is utilized to avoid the PON logic distance constraints. The 10 G Ethernet optical link is used to expand the function of transmission and improve the robustness of the network.%长距离PON接入(LR-PON)技术是NG-PON技术发展的重要方向。由于受逻辑距离限制，在分析典型网络结构的基础上，提出了基于远程协议转换(RPC)技术实现LR-PON的方案。LR-PON的馈线段采用点对点传输协议，而配线段采用PON协议，利用RPC转换，避开了PON逻辑距离的限制，使用10 G以太网光链路来扩展传输功能，提高了网络的鲁棒性。
