Belden Inc. TUSLG048RS2N OS2 48-fiber Riser Cable

Product Description

The BELDEN INC. TUSLG048RS2N is a 48-fiber OS2 single-mode tight-buffer riser-rated optical fiber cable designed for structured cabling installations in commercial and industrial buildings. OS2 single-mode fiber supports long-distance, high-bandwidth data transmission with low signal loss, making it a reliable backbone cabling solution. The tight-buffer construction protects individual fibers during handling and termination. This cable is suited for in-building vertical runs between floors and equipment rooms, installed by licensed low-voltage or data/communications cabling technicians.

This cable is used in riser (CPE) applications where a plenum rating is not required but vertical fire-resistance performance is mandated by code. Typical installations include inter-floor backbone runs in office buildings, data centers, and campus environments where OS2 single-mode fiber is specified for high-capacity fiber optic infrastructure. The 48-fiber count supports high-density patch panel and distribution frame terminations.

Key Features

• 48-fiber OS2 single-mode construction for long-distance, low-loss transmission
• Tight-buffer design simplifies field termination and fiber handling
• Riser-rated (OFCR) jacket meets vertical flame propagation requirements for in-building use
• CPE (customer premises equipment) rated for structured cabling environments
• High fiber count supports dense backbone and distribution cabling layouts

Compatibility

Designed as a riser-rated OS2 single-mode tight-buffer backbone cable for use in commercial structured cabling systems requiring OFCR-rated fiber runs.

Installation Notes

Installation should be performed by a qualified low-voltage or fiber optic cabling technician familiar with TIA-568 and NEC Article 770 requirements. De-energize any adjacent electrical systems and follow building management procedures before routing cable through vertical penetrations. Use appropriate innerduct or conduit fill calculations to avoid overfilling raceways. Do not exceed the cable minimum bend radius during pulling or routing to prevent fiber damage.
