Belden Inc. TU3C0024RR2N 24-fiber OM3 Ofnr Riser Cable

Product Description

The BELDEN INC. TU3C0024RR2N is a 24-fiber indoor multimode fiber optic cable rated for riser (OFNR) installations. Built to OM3 performance standards, this cable supports high-bandwidth applications including 10 Gigabit Ethernet and structured cabling backbones in commercial and industrial buildings. The tight-buffered construction provides durability and ease of termination, making it a practical choice for inside-plant runs between floors and through conduit. Licensed low-voltage and data-cabling contractors typically specify this cable for backbone and horizontal distribution segments where a riser fire rating is required by code.

This cable is suited for indoor vertical riser runs in commercial buildings, data centers, and campus backbone installations. The OM3 multimode designation supports laser-optimized transmission for high-speed networking equipment. The OFNR rating makes it appropriate for installation in vertical shafts and between floors without the need for conduit in jurisdictions that accept riser-rated cabling. It ships as a single unit and is intended for installation by qualified low-voltage or communications cabling professionals.

Key Features

• 24-fiber count supports high-density backbone and distribution cabling runs
• OM3 multimode rating provides laser-optimized performance for 10 Gigabit and higher-speed applications
• OFNR riser fire rating meets NEC Article 770 requirements for vertical indoor runs
• Tight-buffered construction simplifies field termination and connector installation
• Indoor-rated design suitable for conduit, cable tray, and open riser shaft routing

Compatibility

Designed as an OEM-style indoor riser fiber optic cable for use with standard OM3 multimode fiber connectors and patch panels in commercial structured cabling systems.

Installation Notes

Installation should be performed by a licensed low-voltage or communications cabling contractor familiar with TIA-568 and NEC Article 770 requirements. De-energize and secure any adjacent powered systems before working in riser shafts or cable trays. Observe the manufacturer minimum bend radius during pulling and routing to avoid microbend attenuation. Do not use this cable in outdoor or direct-burial applications, as it carries an indoor-only OFNR rating.
