The Huawei FGHF board (more accurately FLHF or CGHF) refers to high-density Optical Line Terminal (OLT) service boards used in Huawei's MA5800 Optical Access Networks, offering features like 10G GPON/XG-PON combo ports for ultra-HD video, smooth evolution to 40G/50G PON, support for IPv4/IPv6, large user capacity, and energy efficiency with low power consumption and intelligent cooling.
Product Features
High-Density Access: Supports 16-port 10G PON (GPON/XG-PON) in a single slot, enabling massive bandwidth for 4K/8K/VR services.
Smooth Evolution: Built on a unified platform, allowing seamless upgrades from GPON to 10G PON and 40G/50G PON without hardware replacement, protecting investments.
IPv4/IPv6 Ready: Supports dual stacks and IPv6 multicast for future-proof networks.
Enhanced Video Experience: Features distributed caching and burst absorption for quick video start-up and channel switching.
Intelligent O&M: Includes video surveillance (VMOS/eMDI) for intelligent troubleshooting and a simplified network operation experience.
Energy Efficiency: Utilizes specialized chips, supports idle board power-off, and has intelligent fan control, significantly reducing power consumption (e.g., <73W for 16 GPON ports).
Application Scenarios
Small-Scale GPON Broadband for Rural Communities & Small SMEs (North America)
A regional telecom operator in the U.S. deployed FGHF interface boards with MA5800-X2 OLTs to expand broadband access across rural areas of Montana, covering 15,000 households and 3,000 small businesses (e.g., farms, local shops). Each FGHF’s 4 GPON ports connected to user-side ONTs, delivering 2.5Gbps downlink for 4K streaming and 1Gbps uplink for remote work/file transfers. The L2 VLAN function isolated residential and business traffic, while QoS prioritized SME point-of-sale (POS) data and video conferencing. With 20 FGHF boards deployed, the operator achieved 20Gbps total access capacity, meeting local bandwidth demands at 45% lower costs than higher-density alternatives—perfectly matching rural small-scale coverage needs.
