Belden Inc. TFSBB006RN5N OS2 6 Fiber Pvc Ofnr Cable

Product Description

The BELDEN INC. TFSBB006RN5N is an OS2 single-mode fiber optic cable rated for 6 fibers with a PVC jacket and OFNR (Optical Fiber Nonconductive Riser) flame rating. It is designed for structured cabling installations where long-distance, low-attenuation signal transmission is required. OS2 single-mode construction supports extended runs typical in campus backbones, data centers, and commercial building risers. The PVC outer jacket and OFNR rating make it suitable for vertical riser pathways between floors in accordance with NEC Article 770 requirements. Licensed low-voltage and datacom installers are the primary trade for this cable.

This cable is suited for riser-rated vertical runs in commercial and institutional buildings. It fits trunk and backbone cabling segments connecting telecom rooms, equipment rooms, and entrance facilities. OFNR-rated fiber is commonly specified on commercial construction jobs where riser fire stop compliance is required between floors. The 6-fiber count supports moderate-density backbone links in both new construction and retrofit applications.

Key Features

Compatibility

Designed as an OEM-style riser-rated OS2 single-mode fiber optic cable for use in structured cabling backbone and riser applications in commercial buildings.

Installation Notes

Installation should be performed by a licensed low-voltage or datacom cabling technician familiar with NEC Article 770 fiber optic wiring methods. De-energize any adjacent copper infrastructure and verify riser firestop requirements before pulling cable through vertical pathways. Observe the manufacturer minimum bend radius during pulling and termination to avoid microbend attenuation. Fusion splicing or field-installable connectors should be used by qualified personnel with appropriate cleaving and splicing equipment.
