Belden Inc. TUSLG036RN2N OS2 Fiber Optic Cable 36F Ofnr

Product Description

The BELDEN INC. TUSLG036RN2N is an OS2 single-mode fiber optic cable with a 36-fiber count, rated OFNR (Optical Fiber Nonconductive Riser) for riser-rated building installations. This cable is designed for low-loss, long-distance data transmission in structured cabling systems. The tight-buffered, multi-loose construction provides mechanical protection and flexibility during installation. It is sold as a single unit (EA) and is intended for installation by licensed low-voltage technicians, data cabling professionals, and licensed electricians working in commercial or industrial environments.

This cable is suited for riser-rated vertical runs between floors in commercial buildings, data centers, and campus backbone applications. OS2 single-mode construction supports high-bandwidth, long-distance runs where multimode cable reaches its limits. The OFNR rating makes it code-compliant for installation in riser shafts and vertical runs without the need for conduit in many jurisdictions. It is typically deployed as part of a structured cabling backbone connecting telecom rooms, equipment rooms, and horizontal distribution points.

Key Features

• OS2 single-mode fiber supports long-distance, low-attenuation transmission
• 36-fiber count suits high-density backbone and campus cabling runs
• OFNR riser rating meets NEC requirements for vertical shaft installations
• Tight-buffered multi-loose construction simplifies termination and handling
• CPE (Customer Premises Equipment) jacket suitable for indoor structured cabling

Compatibility

Designed as an OEM-style riser-rated OS2 single-mode fiber optic cable for use with standard LC, SC, ST, or MTP/MPO terminations in commercial structured cabling systems.

Installation Notes

Installation should be performed by a qualified low-voltage technician or licensed electrician in accordance with NEC Article 770 governing optical fiber cables. De-energize and lock out any adjacent electrical equipment before routing cable through riser shafts or conduit. Observe the minimum bend radius of the cable during pulling and routing to avoid fiber damage. Verify that the OFNR riser rating meets the local authority having jurisdiction requirements before installation in vertical shafts.
