The Huawei FLHF (H901FLHF/H902FLHF) is a high-density, 16-port Flex-PON OLT (Optical Line Terminal) interface board, designed for Fiber-to-the-Home (FTTH) networks, offering multi-PON (GPON, XG-PON, XGS-PON) support on a single board, enabling smooth network upgrades and cost savings, high bandwidth, and intelligent power management for large-scale fiber deployments.
Product Features
Multi-PON Technology: Supports GPON, XG-PON, and XGS-PON on a single port, allowing operators to offer different services and smoothly upgrade to 10G PON.
High Density: Provides 16 ports on one board, increasing connectivity options and space efficiency in OLT chassis.
Flexible Network Evolution: Enables cost-effective upgrades from GPON to 10G PON without replacing ONUs, protecting investments.
High Bandwidth: Delivers ultra-high-speed access, supporting 10G upstream and downstream, ideal for bandwidth-intensive services.
Intelligent Power Management: Features efficient power consumption, using special chips, and supports features like idle board power-off and intelligent fan speed adjustment to reduce energy use.
IPv4/IPv6 Support: Allows smooth transition for networks by supporting both IPv4/IPv6 dual stacks and IPv6 multicast.
Application Scenarios
Large-Scale Residential Broadband Access for Suburban & Rural Areas (North America)
A regional telecom operator in the U.S. deployed FLHF interface boards with MA5800-X7 OLTs to expand its broadband network across suburban and rural areas of Texas, covering 200,000 households and 18,000 small businesses. Each FLHF’s 16 dual-mode (GPON/EPON) ports connected to user-side ONTs, delivering stable 2.5Gbps downlink bandwidth for 4K streaming and remote work. The L2 VLAN function isolated residential and business traffic, while QoS prioritized IPTV and video conferencing. With 75 FLHF boards deployed, the operator achieved 300Gbps total access capacity, reducing OLT slot usage by 40% vs. 8-port boards—all at a cost-effective price point, perfectly matching the region’s broadband coverage needs.
