The Hybrid Fiber XPON ONU is a high-performance Optical Network Unit designed to meet the demands of telecom operators for a variety of applications, including FTTO (office), FTTD (desktop), FTTH (home), SOHO broadband access, and video surveillance. Built on advanced chip technology, this ONU supports Layer 2 and Layer 3 functions, ensuring robust data services for carrier-grade FTTH applications. Engineered for reliability, this ONU operates efficiently across a wide range of temperatures, making it suitable for various environmental conditions. Equipped with a powerful firewall, it enhances network security while ensuring ease of management and maintenance. Its intelligent QoS (Quality of Service) mechanisms guarantee optimal performance across different services. The device adheres to international technical standards, including IEEE 802.3ah and ITU-T G.984, ensuring seamless integration with existing network infrastructures. With its XPON dual-mode capability, the ONU automatically switches between EPON and GPON modes, offering greater flexibility and compatibility with different OLTs. The device features a high-speed Gigabit Ethernet port, ensuring fast and stable wired connections. Its SC single-mode optical interface supports long-distance transmission of up to 20km, with reliable optical power levels for both EPON and GPON standards. Designed for efficiency, the ONU consumes minimal power, operating at less than 4W while being powered by a 12V external AC-DC adapter. It also incorporates intelligent networking features such as rogue ONU detection, auto-configuration, auto firmware upgrades, and comprehensive VLAN support. Additional functionalities include IGMP snooping for multicast traffic optimization, multiple QoS queues with prioritization mechanisms, and extensive IPv4/IPv6 protocol support for modern networking requirements. With an intuitive web interface and support for TELNET and CLI management, the Hybrid Fiber XPON ONU provides telecom operators and ISPs with a scalable, secure, and easy-to-manage solution for next-generation fiber access networks.
