Belden Inc. TU3DK048RN2N OM3 48-fiber Riser Cable

Product Description

The BELDEN INC. TU3DK048RN2N is a 48-fiber OM3 multimode fiber optic cable rated for indoor riser (OFNR) installations. It features a CPE (chlorinated polyethylene) outer jacket, which provides flexibility and resistance to environmental stress in vertical cable runs. This cable is designed for high-bandwidth backbone and horizontal cabling applications in commercial and institutional buildings. Licensed low-voltage or structured cabling technicians handle installation in accordance with applicable codes. The 48-fiber count supports dense connectivity in data centers, telecommunications rooms, and enterprise network infrastructure.

This cable is suited for indoor riser pathways where vertical cable runs pass between floors. The OM3 multimode fiber classification supports 10 Gigabit Ethernet and other high-speed protocols over appropriate distances. It is commonly deployed in building backbone segments connecting main distribution areas to intermediate distribution frames. The OFNR rating makes it compliant for use in riser spaces as defined by the NEC without requiring a plenum-rated substitute where plenum rating is not mandated.

Key Features

• 48-fiber count for high-density backbone and riser runs
• OM3 multimode fiber supports 10 Gigabit Ethernet applications
• OFNR (Optical Fiber Nonconductive Riser) rating for NEC-compliant riser installations
• CPE outer jacket provides flexibility and durability in indoor environments
• Indoor-rated construction designed for vertical cable pathways between floors

Compatibility

Designed as an OEM-style riser fiber optic cable for use with standard OM3 multimode fiber terminations and patch panels in indoor structured cabling systems.

Installation Notes

Installation should be performed by a licensed low-voltage or structured cabling technician following NEC Article 770 requirements for optical fiber cables in riser spaces. Ensure that all active network equipment is powered down before terminating or splicing fiber runs. Observe the minimum bend radius specified for the cable to avoid fiber damage during pulling and routing. Do not substitute this OFNR-rated cable in plenum air-handling spaces where an OFNP rating is required by code.
