下一代PON(无源光网络)标准的研究尤其是MW-PON(多波长PON)已成为未来接入网发展的热点。文章描述了MW-PON系统在光层堆叠多个波长,以增加传统ODN(光分配网络)接入容量的独特思路,分析了MW-PON系统的波长分配、波长调谐、波长资源管理和波长通道性能监控等逻辑功能,重点研究了OLT(光线路终端)端口和ONU(光网络单元)设备功能实体、ONU正常激活和TDM/TDMA(时分复用/时分多址)激活、流氓ONU行为的减轻机制等关键技术。
The research of next-generation PON (Passive Optical Network) standards, especially MW-PON (Multi-wavelength PON), has become a hot spot in the future development of access networks. The paper describes the unique idea of MW-PON system stacking multiple wavelengths at the optical layer to increase the access capacity of traditional ODN (Optical Distribution Network), analyzes wavelength allocation, wavelength tuning, wavelength resource management and wavelength channel Performance monitoring and other logic functions, focusing on the OLT (optical line terminal) port and ONU (optical network unit) device functional entities, ONU normal activation and TDM / TDMA (Time Division Multiplexing / Time Division Multiple Access) activation, rogue ONU behavior mitigation Mechanism and other key technologies.
