C-Data FD600-104GW EPON ONU 4-Port Gigabit Ethernet SC Connector

The C-Data Technology FD600-104GW is an EPON ONU device engineered for broadband access deployments where fiber reach, port density, and compact form factor are priorities. Built around a single EPON uplink port and four auto-negotiating 10/100/1000Base-TX Ethernet interfaces, the unit delivers symmetric 1.25 Gbps PON throughput with a usable downstream of 950 Mbps and upstream of 930 Mbps over distances up to 20 km with a split ratio of 1:64. The aluminum alloy die-cast enclosure provides structural rigidity and passive heat dissipation in a slim 130 × 110 × 24 mm footprint weighing only 0.18 kg, making it equally suited for integration into C-Data outdoor platforms or embedding as a functional module within third-party access network equipment. Full compliance with IEEE 802.3ah and CTC 3.0 ensures broad interoperability with third-party OLTs, while SNMP, Telnet, and local management interfaces give operations teams flexible tools for configuration, alarm handling, and remote software upgrades without a maintenance visit to the field.

Key features & benefits

• Single-Mode EPON Uplink to 20 km — One SC-connector EPON port operating on 9/125 μm single-mode fiber with a 1310 nm transmit wavelength and 1490 nm receive wavelength reaches up to 20 km and supports a 1:64 split ratio, enabling a single fiber run to serve large subscriber populations efficiently.
• Symmetric 1.25 Gbps PON with Sub-1.5 ms Latency — The EPON interface delivers a data rate of 1.25 Gbps symmetrically, with measured PON throughput of 950 Mbps downstream and 930 Mbps upstream and a latency figure below 1.5 ms, keeping latency-sensitive applications responsive across the passive optical network.
• Four Auto-Negotiating Gigabit Ethernet Ports — Four RJ45 ports with Auto MDI/MDI-X support 10/100/1000Base-TX auto-negotiation in full and half duplex modes over standard copper runs up to 100 m, giving subscribers or downstream switches flexible connectivity without manual configuration.
• Dynamic Bandwidth Allocation and QoS — DBA and port-based rate limiting allow operators to allocate upstream capacity dynamically and enforce per-port bandwidth policies, maintaining service quality across mixed-traffic environments without over-provisioning fiber resources.
• Advanced Layer 2 Switching and VLAN Services — Wire-speed Layer 2 switching with VLAN TAG/UNTAG handling, VLAN conversion, port-based VLAN separation, priority classification, broadcast storm resistance, loop detection, and port isolation provide the traffic management capabilities required for multi-tenant and multi-service deployments.
• Comprehensive Remote Management via SNMP — EMS network management over SNMP, supplemented by Telnet and local access, covers status monitoring, configuration management, alarm management, and log management. ONU auto-discovery, link detection, and remote software upgrade reduce the need for on-site intervention.
• Aluminum Alloy Die-Cast Enclosure — The die-cast aluminum alloy shell dissipates heat passively, adds mechanical durability, and keeps the unit within a slim 130 × 110 × 24 mm profile at 0.18 kg, simplifying rack integration or platform mounting in space-constrained deployments.
• Low Power Consumption — Powered by an external 12 V 0.6 A adapter with a maximum consumption below 4.9 W, the FD600-104GW imposes minimal load on existing power infrastructure and is well-suited for installations where total site power budgets are tightly managed.
