摘　　要：从OFDM与PON网络的融合角度出发,介绍了OFDM-PON技术的相关背景与技术方案。着重分析了OFDM-PON网络中上行速率提升的解决方案,提出上行采用OFDMA接入与基于OFDM的TDMA接入两种技术方法,并对两种方案进行了详细的比较。最后,对上行方案做了基于光通信仿真平台VPI验证,仿真结果验证了所提上行方案功能的完整性和可靠性。Focusing on the integration point view of the OFDM and PON network, introduce the technical background and solutions of OFDM-PON. Propose the technical solutions of improving upstream data rate and compare the difference between them, which are the OFDMA access network and TDMA access network based on OFDM. Lastly, based on the VPI optical communication simulation platform, prove the integrity and reliability of the proposed solutions.
