Each GPON port supports a 1:128 splitting ratio, and the system is capable of supporting up to 512 terminals. This product is designed for compact server rooms, meeting the demands for both high performance and space efficiency. It is easy to deploy, convenient to use, and flexible, making it ideal for enhancing network performance, improving reliability, and reducing power consumption in access and enterprise networks. The FD1616S-B0 is suited for a variety of network applications, such as three-in-one broadcast television networks, FTTP (Fiber to the Premise), video monitoring networks, enterprise LANs, IoT (Internet of Things), and more. It offers a high price/performance ratio, making it an attractive solution for a wide range of needs. This product features a dedicated chip, USB interface, backup battery unit, and Layer 3 switching capabilities. It meets ITU-T G.984/G.988 standards and supports the OMCI protocol. With a compact Pizza-Box design, it provides complete PON protection switching functionality and robust Layer 2 switching support. This includes features such as TRUNK, VLAN, LACP, rate limiting, port isolation, queue technology, flow control, and ACL, ensuring reliable multi-service integration. The device also guarantees high-quality service (QoS), including a fully improved DBA to meet the varying QoS requirements for different service flows regarding latency, jitter, and packet loss rate. The FD1616S-B0 includes an easy-to-use management system that supports CLI, WEB, SNMP, TELNET, SSH, and OMCI standards. Through the OMCI channel protocol, users can manage ONT function parameters, T-CONT business lines, Qos settings, performance statistics, event reporting, ONT configuration, and fault diagnostics. The management rack complies with the 1U 19-inch standard, and the uplink port includes four 10/100/1000M auto-negotiation COMBO ports, four SFP interfaces, and two 10-Gigabit SFP+ interfaces. The PON ports, offering 16 slots, support a transmission distance of 20 km and are compatible with ITU-T G.984.2 Class B+/Class C+ standards. Additional features include a backup USB interface for configuration backups, program upgrades, and log recording. The device is powered by either 220VAC or -48DC, consuming a maximum of 100W. Operating in temperatures ranging from -15°C to 50°C and capable of storage temperatures between -40°C and 85°C, it maintains a relative humidity range of 5% to 90% (non-condensing). This product is designed to provide efficient and reliable service in various networking environments, with an emphasis on ease of use, flexibility, and scalability.
