C-Data FD511G-X-F680 Single Port XPON ONU

The C-Data FD511G-X-F680 is a single-port XPON Optical Network Unit (ONU) designed for high-speed fiber-to-the-home (FTTH) broadband access. It is a dual-mode device that automatically switches between GPON and EPON standards based on the local OLT mode. 

Key Specifications

• PON Interface: 1 x XPON port supporting symmetrical 1Gbps rates (up to 2.488Gbps downstream in GPON mode).
• Ethernet Port: 1 x 10/100/1000Mbps auto-negotiation RJ45 LAN port.
• Receiving Sensitivity: -28dBm for XPON and -27dBm for EPON.
• Transmission Distance: Supports a fiber transmission distance of up to 20 km.
• Power Supply: Requires an external 12V/0.5A DC power adapter with a typical consumption of approximately 3W.
• Physical Dimensions: 125 x 80 x 28 mm, weighing approximately 125g. 

Features and Compatibility

• Dual Mode Access: Seamlessly operates in both EPON (IEEE802.3ah) and GPON (ITU-T G.984) modes.
• Third-Party Compatibility: Confirmed by multiple sources to work with major OLT brands including Huawei, ZTE, BDCOM, and Fiberhome.
• Network Management: Supports ONU auto-discovery, link detection, and remote firmware upgrades.
• Advanced Networking: Includes support for VLAN configuration, MAC address learning, port flow control, and IGMP snooping.
