Nokia FGLT-B Overview
The FGLT-B is a dedicated GPON line termination board designed for installation in the 7360 ISAM FX subrack. Compliant with ETSI and ANSI standards, it is specifically engineered for central office (CO) deployment within ISAM FX equipment ecosystems.
Featuring a 1.28 Tb/s switching matrix, the FGLT-B offers termination for 16 GPON ports—supporting 2.488 Gbps downstream and 1.244 Gbps upstream rates—with compatibility for pluggable SFP GPON optical modules.
Product Features
- High Density: 16 GPON interfaces per card, supporting a massive number of subscribers (over 2,000 per card).
- GPON Technology: Uses Passive Optical Network for efficient fiber sharing.
- High Bandwidth: Delivers 2.488 Gbps downstream and 1.244 Gbps upstream speeds per port.
- Service Versatility: Supports IPTV, RF overlay, and various voice/data services (via connected ONTs).
- Advanced Management: Includes QoS (Quality of Service), VLANs, Multicast, Jumbo Frames, and remote management capabilities.
- Compatibility: Designed for Nokia Alcatel-Lucent 7360 ISAM FX OLT platforms.
Application Scenarios
FGLT-B Board: Australian Rural Broadband Expansion Case
In 2025, a major Australian telecom provider deployed the FGLT-B GPON line termination board in 7360 ISAM FX subracks to bridge the digital divide across rural New South Wales and Queensland. The project required ETSI/ANSI-compliant, high-capacity solutions for central office (CO) setups, targeting underserved towns and farms.
Powered by the FGLT-B’s 1.28 Tb/s switching matrix, the board delivered 16 GPON ports (2.488 Gbps down/1.244 Gbps up) with pluggable SFP modules, connecting 250,000+ rural users to stable gigabit broadband. Its long-reach compatibility (up to 60km) simplified deployment across vast distances, while seamless subrack integration reduced setup time. Post-launch, network capacity surged 90%, enabling remote work, telehealth, and agritech applications with zero service outages.
