Belden Inc. TU3LG048R22N OM3 48-fiber Riser Cable

Product Description

The BELDEN INC. TU3LG048R22N is a 48-fiber multimode OM3 indoor fiber optic cable rated for riser (OFNR) installations. It features a tight-buffered construction with a CPE outer jacket, making it suited for vertical runs between floors and inside building risers. OM3 fiber supports high-bandwidth laser-optimized applications including 10 Gigabit, 40 Gigabit, and 100 Gigabit Ethernet over appropriate distances. Licensed electricians and low-voltage cabling technicians are the primary installers for this type of structured cabling product.

This cable is intended for indoor riser environments in commercial and institutional buildings where a high fiber count is required in a single run. Typical applications include backbone cabling between telecom rooms, data center interconnects, and campus riser shafts. The OFNR rating means this cable meets flame-spread requirements for riser pathways without the need for conduit in many jurisdictions. The tight-buffered design simplifies termination and allows individual fibers to be accessed and routed to patch panels or splice enclosures.

Key Features

• OM3 laser-optimized multimode fiber supports 10GbE, 40GbE, and 100GbE applications
• 48-fiber count accommodates high-density backbone and riser runs in a single cable
• OFNR (Optical Fiber Nonconductive Riser) rating for compliant vertical riser installations
• Tight-buffered construction simplifies termination and individual fiber routing
• CPE outer jacket provides flexibility and durability in indoor environments

Compatibility

Designed as an OEM-style riser fiber optic cable for use with standard OM3-compatible fiber optic patch panels, splice enclosures, and termination hardware in indoor structured cabling systems.

Installation Notes

Installation should be performed by a licensed low-voltage cabling technician or qualified electrician familiar with TIA-568 structured cabling standards and applicable local building codes. De-energize any adjacent electrical systems and follow building fire-stop requirements when routing through floor penetrations. Observe the minimum bend radius and maximum pull tension specified by the manufacturer to avoid fiber damage during installation. Do not exceed the cable's rated pulling tension or compress the jacket when securing with cable ties.
