C-Data FD600-104GW EPON ONU with 4 Gigabit Ethernet Ports and 2.4 GHz Wi-Fi
The C-Data FD600-104GW is an EPON optical network unit designed for fiber-to-the-home (FTTH) and fiber-to-the-office (FTTO) broadband access. It combines one EPON optical interface, four Gigabit Ethernet LAN ports, and integrated 2.4 GHz Wi-Fi in a single subscriber terminal.
Designed to operate with an EPON optical line terminal (OLT), the FD600-104GW connects a provider's passive optical network to local wired and wireless devices. Its Ethernet ports support computers, switches, and other network equipment, while IEEE 802.11b/g/n Wi-Fi provides wireless access at a maximum advertised link rate of 300 Mbps.
Key Features
- One EPON optical interface for fiber broadband access.
- Four RJ45 LAN ports supporting 10/100/1000 Mbps auto-negotiation.
- Integrated 2.4 GHz IEEE 802.11b/g/n Wi-Fi with an advertised link rate up to 300 Mbps.
- IEEE 802.3ah and CTC 3.0 protocol support.
- Dynamic Bandwidth Allocation (DBA) and port-based bandwidth control.
- VLAN tagging, untagging, conversion, and port isolation.
- Remote management, monitoring, and software upgrade functions.
EPON Fiber Access
The optical interface supports a symmetric 1.25 Gbps EPON line rate. The manufacturer documents transmission distances up to 20 km and a split ratio up to 1:64, subject to the optical loss budget and network design. Available subscriber bandwidth depends on the provider's service profile and shared PON capacity.
Wired and Wireless Connectivity
Four Gigabit Ethernet ports provide local wired connections with auto-negotiation and auto MDI/MDI-X. Integrated 2.4 GHz Wi-Fi supports compatible 802.11b/g/n clients. Actual wireless throughput depends on client capabilities, interference, signal conditions, and configuration.
Network Management
The FD600-104 series supports ONU discovery, link detection, remote software upgrades, SNMP and Telnet management, and local administration. VLAN controls, traffic prioritization, broadcast storm control, and loop detection help operators configure subscriber services. Feature availability depends on firmware and OLT provisioning.
Power and Installation
The ONU uses an external 12V DC power adapter. PoE input and PoE output are not documented. Install the unit in a protected location within its specified environmental limits; no outdoor weatherproof rating has been verified.
Ideal Applications
- Residential FTTH subscriber connections.
- Small-office FTTO broadband access.
- EPON deployments requiring four wired LAN connections and integrated Wi-Fi.
- Provider-managed fiber access with VLAN and bandwidth controls.
Compatible Products
The FD600-104GW is intended for IEEE 802.3ah EPON networks. Its documentation references CTC 3.0 support, but compatibility with a particular OLT must be confirmed for the ONU hardware revision, firmware version, authentication method, and service configuration.
No specific OLT model has been verified for an unconditional compatibility recommendation.
- Wired client equipment using 10/100/1000 Mbps RJ45 Ethernet interfaces.
- Wireless clients supporting 2.4 GHz IEEE 802.11b/g/n and a matching configured security mode.
Important: Do not substitute a GPON-only or XGS-PON-only connection for EPON. Confirm OLT registration support, optical power levels, fiber loss, VLAN provisioning, and service profiles before deployment. The optical connector is documented as SC, but its UPC/APC polish is not reliably confirmed for the stocked revision.
Power compatibility: Use the power supply specified for the actual unit. A replacement requires confirmation of voltage, current capacity, connector dimensions, and polarity. Do not connect a passive PoE injector on the assumption that this ONU accepts PoE.
