Belden FF3U12LD Fxu Frame OM3 12-port Lc Duplex Panel

Product Description

The Belden FF3U12LD is an FXU-series rack-mount fiber optic patch panel configured for 12 LC duplex ports on an OM3 multimode fiber backbone. The panel provides a structured termination point for OM3 50/125 multimode fiber runs, organizing patch connections at the distribution frame level. Designed for data centers, telecommunications rooms, and structured cabling installations, this unit is typically installed by low-voltage cabling technicians and network infrastructure specialists who require reliable, high-density fiber management in a rack-mount footprint.

The FF3U12LD fits into Belden FXU-series frames and supports OM3 multimode fiber — the standard for 10 Gigabit Ethernet runs up to 300 meters. With 12 LC duplex ports, it supports up to 24 fiber strands per panel. This configuration is common in enterprise LAN backbone applications, server room fiber distribution, and horizontal-to-backbone transition points where organized, labeled fiber termination is required.

Key Features

• 12 LC duplex ports supporting up to 24 individual OM3 fiber strands
• Compatible with Belden FXU frame system for modular rack-mount deployment
• OM3 50/125 multimode fiber designation for 10GbE and higher-speed applications

• Sold as a single unit (EA), suitable for incremental panel-by-panel buildout

Compatibility

Designed for use within the Belden FXU frame system with OM3 multimode fiber cabling and LC duplex patch cords. No additional specific compatible model numbers were provided in the product data.

Installation Notes

Installation is performed by qualified low-voltage cabling technicians in accordance with TIA-568 structured cabling standards. Prior to installation, verify the host FXU frame is de-energized and that all fiber runs are properly labeled and slack-managed before seating the panel. Avoid bending fiber cables below the minimum bend radius during routing. Fiber end-faces should be cleaned and inspected with appropriate optical tools before mating connectors.
