Belden Inc. TF3LG012R25N OM3 12 Fiber Pvc Ofnr Cable

Product Description

The BELDEN INC. TF3LG012R25N is a tight-buffered multimode OM3 fiber optic patch cable rated for indoor riser (OFNR) installations. Constructed with a 12-fiber count and a PVC outer jacket, this cable is designed for structured cabling systems where high-bandwidth, short-to-medium-distance optical transmission is required. OM3 fiber supports 10 Gigabit Ethernet applications over standard distances and is compatible with 850 nm VCSEL laser sources. Licensed network technicians and low-voltage cabling contractors are the primary installers for this product.

This cable is suited for use in commercial and enterprise environments where indoor riser-rated fiber runs are required between floors or through vertical pathways. Typical applications include backbone cabling in data centers, server rooms, and telecommunications closets. The 12-fiber configuration supports multiple simultaneous transmission paths within a single cable run, making it efficient for high-density structured cabling deployments.

Key Features

• OM3 multimode fiber supports 10 Gigabit Ethernet at standard OM3 distances
• 12-fiber count enables high-density installations in a single cable
• PVC jacket provides durable protection for indoor environments
• OFNR (Optical Fiber Nonconductive Riser) rating meets NEC riser installation requirements
• Tight-buffered construction simplifies termination and handling

Compatibility

Designed as an OEM-style replacement or direct-install option for indoor riser multimode OM3 fiber patch cable applications in structured cabling systems.

Installation Notes

Installation should be performed by a qualified low-voltage cabling technician familiar with NEC Article 770 requirements for optical fiber cabling. De-energize connected network equipment before making or breaking fiber connections. Avoid bending the cable below its minimum bend radius during routing and termination. Use appropriate fiber-rated innerduct or conduit when routing through building pathways.
