Nokia FWLT-B Board

Nokia FWLT-B Overview

Product Features

• Technology: Universal Next Generation PON (U-NGPON), supporting XGS-PON (10G/10G, 10G/2.5G) and TWDM-PON (10G/10G, 10G/2.5G).
• Ports: 8 physical XFP ports for PON links, enabling high-density connectivity.
• Bandwidth: High backplane bandwidth (e.g., 160 Gbps) and packet forwarding rate (e.g., 36 Mpps) for high-speed data.
• Flexibility: Coexists with GPON/EPON, simplifies network upgrades, and supports different wavelength constellations.
• Management: Comprehensive management and control functions for easy monitoring and configuration.
• Physical: Hot-swappable, fits in Nokia 7360 ISAM FX shelves, with status LEDs. 

Application Scenarios

FWLT-B Board: European Metro 10G PON Upgrade Case
In 2025, a major European telecom operator deployed Nokia’s FWLT-B line termination cards in 7360 ISAM FX platforms across Paris, Berlin, and Madrid. Aimed at scaling 10G broadband and enterprise services, the project leveraged the FWLT-B’s 1.28Tb/s switching matrix for high-capacity data routing.
With 8 XGS-PON/TWDM-PON ports (10 Gb/s each), the card supported dual-rate 10G symmetric/asymmetric services and coexisted with legacy GPON. Its flexible wavelength constellations cut TWDM-PON entry costs by 30%, while the 1.28Tb/s matrix ensured smooth traffic handling for 350,000+ users. Post-upgrade, network capacity rose 85%, latency stayed under 4ms, and the operator efficiently rolled out 10G plans to capture new revenue.
