C-Data FD504GW-DG-HZ410 GPON ONU Dual-Band Wi-Fi 4-Port Gigabit

The C-Data Technology FD504GW-DG-Z410 is a GPON Optical Network Unit (ONU) engineered for Fiber-to-the-Home and Fiber-to-the-Office deployments requiring high-capacity broadband access with integrated dual-band wireless. Compliant with ITU-T G.984.1/2/3/4 standards and supporting Class B+ optical budgets, the unit delivers 2.488 Gbps downstream and 1.244 Gbps upstream over a single-mode fiber infrastructure at distances up to 20 km with split ratios up to 1:128. Four Gigabit Ethernet RJ45 ports serve wired clients, while an 802.11 a/b/g/n/ac dual-band radio provides simultaneous 2.4 GHz and 5 GHz wireless connectivity. A comprehensive management stack—OMCI, TR-069, SNMP, and web UI—simplifies provisioning, monitoring, and remote firmware upgrades in both residential and small-to-medium enterprise environments. Features such as Dynamic Bandwidth Allocation, ACL-based packet filtering, VLAN tagging, multicast snooping, AES encryption, and QoS support make the FD504GW-DG-Z410 well suited for converged data and video service delivery over modern GPON networks.

Key features & benefits

• GPON Class B+ Optical Interface — Conforms to FSAN G.984.2 Class B+ with a 28 dB link budget, 20 km reach, and a maximum split ratio of 1:128, enabling cost-effective fiber infrastructure shared across large subscriber bases.
• High-Throughput PON Performance — Delivers 2.488 Gbps downstream and 1.244 Gbps upstream with a packet loss ratio below 1×10⁻¹² and end-to-end latency under 1.5 ms, supporting demanding video and data services without perceptible degradation.
• Dual-Band 802.11ac Wi-Fi — Integrated 2.4 GHz and 5 GHz radios compliant with 802.11 a/b/g/n/ac provide flexible wireless coverage with strong penetration characteristics for both open-plan and partitioned environments.
• Four-Port Gigabit Ethernet LAN — Four 10/100/1000 Mbps auto-negotiating RJ45 ports with Auto MDI/MDI-X and full/half duplex support connect wired devices at up to 100 m, eliminating the need for additional switches in small deployments.
• Comprehensive QoS and Traffic Management — Dynamic Bandwidth Allocation, ACL-based packet filtering, VLAN tag/untag, multicast snooping and proxy, device-based rate limiting, and MAC-address filtering give operators granular control over service quality and network segmentation.
• Multi-Mode Remote Management — OMCI, TR-069, SNMP-based EMS, and web management interfaces support ONU auto-discovery, link detection, remote software upgrades, alarm management, and configuration management from a single operations center.
• AES Security and Access Control — Hardware AES encryption/decryption and URL access control protect subscriber traffic over the shared PON medium, maintaining confidentiality without sacrificing throughput.
• Flexible Internet Access Modes — Support for DHCP, PPPoE, and Static IP internet modes allows the unit to integrate seamlessly into diverse carrier provisioning architectures without requiring additional CPE modifications.
