Belden Inc. TF3C0012RX5N OM3 12-fiber Pvc Ofnr Cable

Product Description

The BELDEN INC. TF3C0012RX5N is a TF CLT (tight-buffered, central loose tube) OM3 multimode fiber optic cable rated for indoor use with a PVC jacket and OFNR (Optical Fiber Nonconductive Riser) flame rating. The 12-fiber construction supports high-bandwidth data transmission at 850 nm wavelengths, making it suitable for structured cabling installations in commercial and industrial buildings. This cable is designed for pulls through riser spaces between floors, where compliance with OFNR fire rating requirements is required by code. Low-voltage and datacom contractors handle this type of installation.

This cable is used in indoor riser applications within commercial buildings, data centers, and campus environments where a 12-fiber OM3 multimode backbone is required. OM3 glass supports 10 Gigabit Ethernet at distances up to 300 meters and is compatible with LC, SC, and ST connectors commonly used in structured cabling systems. It is suited for both new construction and retrofit pulls in vertical cable pathways.

Key Features

• OM3 50/125 micrometer multimode glass fiber supports 10GbE and higher data rates
• 12-fiber count in a single jacket for efficient backbone routing
• PVC outer jacket rated OFNR for compliant riser installations
• Indoor-rated construction designed for dry, conditioned building environments
• Nonconductive fiber construction eliminates ground loop concerns

Compatibility

Designed as an OEM-style replacement or standard-specification indoor riser fiber optic cable for 12-fiber OM3 multimode structured cabling applications.

Installation Notes

Installation should be performed by a licensed low-voltage or datacom contractor familiar with TIA-568 and NFPA 70 (NEC) Article 770 requirements for optical fiber cables in riser spaces. De-energize any adjacent powered systems before beginning a cable pull in shared pathways. Observe the manufacturer minimum bend radius and maximum tensile load rating during the pull to avoid microbend attenuation. Terminate with fusion splicing or field-installable connectors appropriate for OM3 multimode glass.
