The FD1208S-R1 is a 1U high, 19-inch rack-mounted product that stands out for its compact, flexible, and high-performance design, making it an ideal solution for environments with limited space. It is perfect for deploying in a variety of applications, such as "Triple-Play," CPN, IP cameras, Enterprise LAN, and IoT systems. This OLT provides excellent scalability and ease of deployment, allowing for seamless integration in both small and larger-scale networks. The FD1208S-R1 features one USB interface, four copper Gigabit Ethernet (GE) ports, four optical GE ports, eight EPON ports for downstream connections, and four 10Gb uplink interfaces. It supports up to 512 ONUs with a 1:64 splitter ratio, ensuring robust and reliable connectivity for a wide range of devices. With dimensions of 440mm x 296mm x 44mm and a weight of 4.5kg, the FD1208S-R1 is a compact yet powerful device that doesn't compromise on performance. Its 12 uplink ports include four auto-negotiable 10/100/1000M copper ports, four 10Gb optical interfaces, and eight PON ports, which use SFP slots for enhanced flexibility. It also features one USB Type-C port for ease of connectivity and management, along with a 100BASE-TX outband port and a console port for simplified administration. The PON port specification ensures a transmission distance of up to 20 km, with speeds of 1.25Gbps, and a wavelength of 1490nm for transmission and 1310nm for reception, while the 10Gb SFP+ port supports transmission up to 10 km. This device operates using SNMP, Telnet, and CLI management modes, offering comprehensive management functions such as fan group detection, port status monitoring, VLAN configuration, RSTP, IGMP, QOS, and EPON management. It supports dynamic bandwidth allocation (DBA), ONU authorization, and various QoS configurations, ensuring optimal network performance. The FD1208S-R1 is built with resilience in mind, supporting features like broadcast storm resistance, power-off alarm, and robust system stability during breakdowns. It is also compatible with the IEEE 802.3ah standard, supporting up to 20 km of transmission distance, port-based rate limitation, and data encryption for secure communication. Additionally, the FD1208S-R1 offers both static and dynamic multicast support, RIP routing protocol, and flexible static unicast configuration for seamless data transmission. The system's backplane bandwidth is 116Gb, providing ample capacity for demanding operations. It supports both AC (100V–240V, 47/63Hz) and DC (-36V to -72V) power supply options, with a maximum power consumption of 58W. Designed to withstand diverse environmental conditions, the FD1208S-R1 operates within a temperature range of 0 to 50°C and can be stored at temperatures between -40 and 85°C, with an operating humidity range of 10% to 90% (non-condensing).
