C-Data FD504GW-DG-HZ410 GPON ONU with Gigabit Ethernet and Dual-Band Wi-Fi
The C-Data FD504GW-DG-HZ410 is a GPON optical network unit for fiber-to-the-home and fiber-to-the-office installations. It combines a single-mode GPON optical connection, four Gigabit Ethernet LAN ports, and 2.4 GHz / 5 GHz wireless networking in one subscriber device.
Designed for provisioned GPON broadband services, this ONU connects wired and wireless equipment to the operator's fiber access network. Its management and traffic-control features support service deployment, monitoring, and maintenance.
Key Features
- One Class B+ GPON optical interface.
- Four 10/100/1000 Mbps RJ45 Ethernet ports.
- Dual-band 2.4 GHz and 5 GHz Wi-Fi.
- IEEE 802.11a/b/g/n/ac wireless standards.
- OMCI, TR-069, and web-based management.
- VLAN tagging and untagging, port binding, and multicast snooping/proxy.
- DHCP, PPPoE, and static IP Internet connection modes.
- 12 V DC operation with listed power consumption below 7 W.
GPON Fiber Access
The GPON interface is specified for nominal downstream and upstream line rates of 2.488 Gbps and 1.244 Gbps, respectively. Actual subscriber bandwidth depends on the service plan, OLT configuration, shared PON capacity, and network conditions.
The optical connection is listed as SC/PC for single-mode fiber. Match the connector finish and optical power levels to the installed fiber network before connection.
Wired and Wireless Connectivity
Four auto-negotiating Gigabit Ethernet ports provide connections for computers, switches, routers, and other Ethernet equipment. Integrated dual-band Wi-Fi supports compatible wireless clients on the 2.4 GHz and 5 GHz bands.
Each Ethernet port supports a maximum link speed of 1 Gbps. Neither the GPON line rate nor the wireless standard guarantees equivalent application throughput to an individual device.
Network Management and Traffic Control
Management options include OMCI, TR-069, and a web interface. Supported functions include status monitoring, configuration management, alarms, logs, and remote software upgrades.
VLAN handling, port binding, bandwidth limitation, access-control filtering, and multicast features help operators configure subscriber services.
Power
The listing specifies an external 12 V DC, 1 A power adapter and device consumption below 7 W. Use the correct adapter for the supplied unit; replacement adapter connector dimensions and polarity must be verified.
Ideal Applications
- Residential FTTH broadband access.
- Small-office FTTO connections.
- Subscriber installations requiring wired and wireless connectivity.
- Operator-managed Internet and IP video services over GPON.
Compatible Products
LAN expansion requires standard Ethernet equipment connected to one of the ONU's RJ45 LAN ports. Use suitable Ethernet cabling and configure VLANs and addressing as required by the service.
- MikroTik RB260GS / CSS106-5G-1S Gigabit Ethernet Smart Switch – Connects through a 10/100/1000 Mbps RJ45 port to expand wired LAN connectivity. Power the switch separately; this connection does not supply PoE.
GPON compatibility: The optical uplink requires a compatible GPON OLT, correct subscriber registration, matching service profiles, and suitable optical power levels.
Important: GPON standards compliance alone does not guarantee interoperability with every OLT or Internet provider. Confirm approval, authentication requirements, firmware support, OMCI behavior, and VLAN provisioning before purchase. Do not assume EPON or XGS-PON operation.
