Belden Inc. TU3D9006RN2N OM3 6-fiber Indoor Riser Cable

Product Description

The BELDEN INC. TU3D9006RN2N is an OM3 multimode indoor fiber optic cable rated for riser (OFNR) installations. This cable carries optical data signals through a 6-fiber construction housed in a tight-buffered, duplex-capable design with a CPE-grade outer jacket. It is suited for structured cabling installations in commercial and industrial buildings where riser fire ratings are required by code. Low-voltage and data network technicians install this cable in vertical backbone runs between floors. The OFNR rating meets the fire propagation requirements of the National Electrical Code for riser applications.

This cable is used in indoor vertical riser pathways within commercial office buildings, data centers, hospitals, and educational facilities. It supports OM3 laser-optimized multimode transmission, making it appropriate for high-speed network backbone segments connecting telecommunications rooms to equipment rooms. Installers specify it for runs requiring a non-conductive, tight-buffered fiber solution where riser-rated jacket materials are mandated.

Key Features

• OM3 laser-optimized multimode fiber supports high-bandwidth network applications
• 6-fiber construction provides multiple channel capacity in a single cable run
• OFNR riser rating meets NEC Article 770 requirements for vertical installations
• Tight-buffered construction protects individual fibers and simplifies termination
• CPE-grade jacket provides durability for indoor plenum-adjacent environments

Compatibility

Designed as an OEM-style indoor riser fiber optic cable compatible with standard OM3 multimode patch panels, connectors, and fiber distribution hardware used in structured cabling systems.

Installation Notes

Installation should be performed by a qualified low-voltage or data cabling technician familiar with TIA-568 and NEC Article 770 requirements. Verify riser pathway fire stop requirements before pulling cable through floor penetrations and restore all firestop assemblies after installation. Do not exceed the cable minimum bend radius or maximum pull tension during installation. Terminate fibers using appropriate OM3-rated connectors and test with a compatible OTDR or optical power meter after installation.
