Belden Inc. TF3LG048RN5N OM3 48-fiber Riser Cable

Product Description

The BELDEN INC. TF3LG048RN5N is a tight-buffered, multimode OM3 fiber optic cable rated for indoor riser (OFNR) installations. It houses 48 individual fibers in a PVC jacket, making it a practical choice for backbone and vertical runs between floors in commercial buildings. OM3 laser-optimized multimode fiber supports high-bandwidth applications including 10 Gigabit Ethernet and beyond over appropriate distances. The tight-buffered construction protects individual fibers during handling and termination, reducing the need for breakout kits in many field-termination scenarios. Network technicians and low-voltage contractors are the primary installers for this type of cable.

This cable is suited for indoor vertical riser pathways in commercial and enterprise environments. Typical applications include inter-floor backbone runs in office buildings, data centers, and campus facilities where a high fiber count is required in a single cable run. The OFNR rating means it meets National Electrical Code requirements for riser-rated fire resistance, making it appropriate for installation in building vertical shafts and conduit runs between floors without the need for a plenum-rated substitute in riser-only pathways.

Key Features

• OM3 laser-optimized multimode fiber supports 10GbE and high-bandwidth data transmission
• 48-fiber count in a single cable for high-density backbone installations
• Tight-buffered design simplifies field termination and individual fiber handling
• PVC outer jacket rated OFNR for compliant indoor riser installations per NEC requirements
• Indoor-rated construction appropriate for conduit and cable tray in commercial buildings

Compatibility

Designed as an indoor riser-rated OM3 multimode fiber cable suitable for use with standard LC, SC, and ST multimode connectors and termination hardware in commercial structured cabling systems.

Installation Notes

Installation should be performed by a licensed low-voltage or communications contractor familiar with TIA-568 structured cabling standards and local NEC riser pathway requirements. Observe the cable's minimum bend radius and maximum pull tension during installation to avoid fiber damage. Power down active network equipment before making connections at patch panels or equipment ports. Do not install this OFNR-rated cable in plenum air-handling spaces where a plenum-rated (OFNP) cable is required by code.
