The Huawei FLSF Flex-PON Board is a high-performance 16-port OLT interface board designed for MA5800-X2/X7/X15/X17 platforms. It enables hybrid access of GPON, XG-PON, and XGS-PON (10G symmetric) with upstream/downstream speeds up to 9.953 Gbit/s. Reusing existing ODN resources, it supports 256 ONTs per port, 40km transmission, and 1588v2 synchronization—ideal for gigabit broadband, 4K/8K video, and smart home services.
Product Features
Multi-Mode Compatibility: Seamlessly supports GPON, XG-PON, XGS-PON, and combo access via flexible SFP modules.
High-Speed Performance: Symmetric 10G XGS-PON speeds (9.953 Gbit/s up/down) and 2.488 Gbit/s for GPON.
Extended Reach & Capacity: 40km maximum transmission distance, 256 ONTs per port, and 131,072 MAC addresses.
Reliable Protection: Supports Type B/C (single/dual-homing) protection and bidirectional FEC.
Energy-Efficient: Features high-temperature automatic shutdown and service board energy conservation.
Application Scenarios
Medium-Scale GPON Broadband Access for Suburban Communities & SMEs (Europe)
A regional telecom operator in Italy deployed FLSF interface boards with MA5800-X7 OLTs to upgrade its suburban broadband network, covering 60,000 households and 8,000 small-to-medium enterprises (SMEs) across 7 cities. Each FLSF’s 8 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 SME traffic, while QoS prioritized SME video conferencing. With 40 FLSF boards deployed, the operator achieved 80Gbps total access capacity, meeting peak demands at 30% lower costs than high-density alternatives—perfectly matching the region’s medium-scale coverage needs.
