Belden Inc. TFSLG072R25N 72-fiber OS2 Pvc Ofnr Cable

Product Description

The BELDEN INC. TFSLG072R25N is a tight-buffered, multi-loose-tube OS2 single-mode optical fiber cable rated for indoor riser (OFNR) installations. This 72-fiber cable uses a PVC jacket and meets OS2 single-mode specifications, making it well suited for long-distance, low-attenuation data and communications runs inside commercial and industrial buildings. Licensed low-voltage technicians, structured cabling installers, and network infrastructure contractors are the primary trades that specify and install this cable.

This cable is designed for backbone and riser pathway applications where a high fiber count in a compact, code-compliant jacket is required. Its OFNR rating makes it appropriate for installation through vertical shaft spaces and between floors in multi-story commercial buildings. The OS2 single-mode design supports extended transmission distances at 1310 nm and 1550 nm wavelengths, which is common in enterprise LAN backbones, campus interconnects, and data center riser segments.

Key Features

• OS2 single-mode fiber optimized for long-distance, low-attenuation transmission
• 72-fiber count supports high-density backbone and riser installations
• OFNR (Optical Fiber Nonconductive Riser) rating for code-compliant vertical runs
• PVC outer jacket provides durability in indoor conduit and cable tray environments
• Tight-buffered multi-loose-tube construction eases field termination and mid-span access

Compatibility

Designed as an OEM-style riser-rated optical fiber cable for use with standard OS2 single-mode connectors and splice enclosures in indoor commercial and industrial structured cabling systems.

Installation Notes

Installation should be performed by a qualified low-voltage or structured cabling technician in accordance with ANSI/TIA-568 standards and applicable local codes. De-energize and lock out any adjacent electrical systems before pulling cable through shared pathways. Observe the manufacturer-rated minimum bend radius and maximum pull tension during installation to avoid microbend attenuation. Terminate only with tooling and connectors rated for OS2 single-mode fiber.
