Next Generation UFOM Using Carrier Ethernet Technology discusses using carrier Ethernet technology to provide a next generation UFOM (unified fiber optic multiplexer). It proposes using Ethernet standards like 802.1ad QinQ tagging, E-Line/E-Tree/E-LAN topologies, and hierarchical QoS to improve scalability, flexibility, and performance. It also discusses enhancements like improved OAM, synchronization, protection mechanisms, and quality of service features to enable services like IPTV and mobile backhaul.
