Belden Inc. TF3LG072R25N OM3 72-fiber Pvc Ofnr Cable

Product Description

The BELDEN INC. TF3LG072R25N is a tight-buffered multimode OM3 fiber optic cable rated for 72 fibers with a PVC jacket and OFNR (Optical Fiber Nonconductive Riser) flame rating. Designed for indoor riser installations, this cable carries high-bandwidth optical signals between floors and through vertical pathways in commercial and industrial buildings. The OM3 multimode designation supports 10 Gigabit Ethernet and other high-speed protocols over standard multimode transceivers. Network technicians and low-voltage contractors install this cable in structured cabling systems where a dense fiber count and riser-rated jacket are required by code.

This cable is suited for indoor riser runs in commercial office buildings, data centers, campus backbone segments, and industrial facilities requiring high fiber-count multimode infrastructure. The 72-fiber count makes it appropriate for high-density distribution points, main distribution frames (MDFs), and intermediate distribution frames (IDFs) where multiple runs must be consolidated into a single cable pathway. Installation typically follows TIA-568 structured cabling standards.

Key Features

• OM3 multimode fiber supports 10 Gigabit Ethernet and high-bandwidth applications
• 72-fiber count consolidates high-density runs into a single cable
• PVC jacket with OFNR flame rating meets riser installation requirements
• Tight-buffered construction simplifies termination and reduces bend sensitivity at splice points
• Indoor riser rating suitable for vertical runs between floors per NEC Article 770

Compatibility

Designed as an OEM-style riser-rated multimode fiber optic cable for use in structured cabling systems requiring OM3-grade 72-fiber indoor riser installations.

Installation Notes

Installation should be performed by a licensed low-voltage contractor or certified fiber optic technician following NEC Article 770 and applicable TIA-568 standards. Disconnect and de-energize any active equipment connected to the fiber pathway before beginning termination work. Observe the cable minimum bend radius during pulling and routing to avoid signal loss or fiber damage. Do not exceed the cable rated pulling tension during installation.
