C-Data FD1208S-R1 8-Port EPON OLT 12 Uplink 116Gbps Rack Mount

The C-Data FD1208S-R1 is a 1U, 19-inch rack-mount EPON Optical Line Terminal designed for space-constrained deployments where port density and deployment flexibility are priorities. It delivers 8 downstream EPON PON ports capable of supporting up to 512 ONUs at a 1:64 split ratio, combined with a rich uplink portfolio of 4 copper GE RJ45 ports, 4 optical GE ports, and 4 10GE SFP+ uplink ports—providing a total of 12 uplink interfaces and a 116G backplane bandwidth. Compliant with IEEE 802.3ah, the FD1208S-R1 suits Triple-Play service delivery, CPN, IP camera networks, enterprise LAN buildouts, and IoT infrastructure. Management is handled through SNMP, Telnet, and CLI, with a full suite of Layer-2 switching functions including VLAN, RSTP, IGMP, and QoS, as well as Layer-3 static and dynamic routing capabilities. Dual power supply options—AC and DC—add resilience for varied facility environments.

Key features & benefits

• 8-Port EPON Downstream with High Split Ratio — Eight EPON SFP slots support up to 512 ONUs at a 1:64 splitting ratio over a maximum transmission distance of 20 km using 9/125 μm single-mode fiber, making this OLT well suited for large-scale last-mile fiber access deployments.
• Rich 12-Port Uplink Portfolio — Four copper 10/100/1000M auto-negotiating RJ45 ports, four optical GE interfaces, and four 10GE SFP+ ports give network designers the flexibility to aggregate traffic over copper or fiber at gigabit and 10-gigabit speeds simultaneously.
• IEEE 802.3ah EPON Compliance — Full compliance with IEEE 802.3ah ensures standards-based interoperability, while built-in Dynamic Bandwidth Allocation (DBA), ONU auto-discovery, link detection, and remote software upgrade simplify ongoing network operations.
• Comprehensive Layer-2 Switching — Supports 4096 VLANs, 802.3ad trunk, RSTP, IGMP Snooping, QoS based on port, VID, TOS and MAC address, and port-based flow control—providing the switching fabric required for multi-service carrier and enterprise environments.
• Layer-3 Routing Support — Static unicast and multicast routing, RIP routing protocol, and dynamic multicast with active source support give the FD1208S-R1 routing capability beyond a pure Layer-2 access device.
• Flexible Management Interfaces — SNMP, Telnet, and CLI management modes are complemented by a dedicated 100BASE-TX out-of-band management port, a CONSOLE port, and a USB Type-C interface, enabling both in-band and out-of-band administration from day one.
• Dual AC/DC Power Input — Accepts 100–240V AC at 47/63 Hz or -36V to -72V DC input, consuming just 58W, allowing deployment in standard commercial facilities as well as traditional telecom equipment rooms with -48V DC plant power.
• Compact 1U Form Factor — At 440 × 296 × 44 mm and 4.5 kg, the FD1208S-R1 occupies a single rack unit and is well suited for compact equipment rooms, edge POP sites, and distributed access locations where physical space is at a premium.
