摘　　要：本文针对传统的PON技术对专用联网能力支持不足的问题,阐述了基于环的PON技术支持物理层LAN仿真及增强专用联网能力的优势。详细地讨论了基于环的TDM-PON、基于环的WDM-PON及基于环的混合PON(H-PON)的结构、工作原理、关键技术及相应的验证实验。最后,讨论了在不改变传统PON物理拓扑基础上,用混合PON(WDM/0FDM-PON)技术构建VPN虚拟环链路来解决PON内和PON间的VPN仿真传输。基于环的PON适合高可靠。This paper describes a new ring-based Passive Optical Network （PON） technology which has the advantage of supporting physical layer LAN emulation and enhancing ability of Private Network due to the some of the limitations of traditional PON technology supporting private networking. Many aspects have been discussed in detail such as the architecture, mechanism, key technologies and related verification experiment for ring-based TDM-PON, WDM-PON and Hybrid PON （H-PON）. In final the establishment of VPN virtual ring link by using hybrid PON （WDM/OFDM-PON） technology to solve the VPN emulation transport among intra PONs and inter PONs without change of traditional PON physical layer topology has been discussed. The ring-based PON technology is well suitable for the access network which needs the requiremen~ of high reliability and high security.
