Belden Inc. TUSLF004RN2N OS2 4-fiber Optic Cable Ofnr

Product Description

The BELDEN INC. TUSLF004RN2N is an OS2 single-mode, tight-buffered, multi-loose-tube fiber optic cable rated for riser (OFNR) installations. It houses 4 individual fibers in a compact cable profile designed for low-loss, long-distance signal transmission in structured cabling systems. The tight-buffered construction protects each fiber and simplifies termination. This cable is installed by licensed low-voltage technicians, network cabling contractors, and data communications professionals working in commercial and industrial environments.

This cable is suited for backbone and riser runs inside buildings where a riser fire rating is required by code. The OS2 single-mode fiber supports high-bandwidth, long-haul data and telecommunications links. Typical applications include inter-floor vertical cable runs, data center backbone segments, telecom rooms, and campus distribution systems. The 4-fiber count accommodates small to mid-scale installations where channel count is limited and routing space is at a premium.

Key Features

• OS2 single-mode fiber optimized for long-distance, low-attenuation transmission
• Tight-buffered construction simplifies field termination and protects individual fibers
• OFNR riser rating meets NEC Article 770 requirements for vertical runs between floors
• 4-fiber configuration suits backbone and low-channel-count structured cabling deployments
• Sold per individual unit (each)

Compatibility

Designed as an OEM-style riser fiber optic cable for use in single-mode OS2 structured cabling systems requiring OFNR-rated backbone cable.

Installation Notes

Installation should be performed by qualified low-voltage or data communications cabling technicians in accordance with NEC Article 770 and applicable local codes. De-energize any associated active equipment before terminating or splicing. Observe the cable minimum bend radius during pulling and routing to prevent fiber damage. Do not exceed the cable rated tensile load during installation pulls.
