Belden Inc. TU3LG072RI2N OM3 72-fiber Plenum Cable

Product Description

The BELDEN INC. TU3LG072RI2N is a multimode OM3 72-fiber indoor plenum-rated fiber optic cable designed for high-density structured cabling installations. It carries the CPE (Customer Premises Equipment) designation and uses an OFCR (Optical Fiber Conductive Riser) or equivalent plenum construction suited for air-handling spaces. With 72 fibers in a tight-buffered multimode OM3 configuration, this cable supports high-bandwidth applications including 10 Gigabit Ethernet and backbone runs in commercial and enterprise environments. Installation is typically performed by licensed low-voltage or data cabling contractors.

This cable is intended for indoor use in commercial buildings, data centers, and campus backbone infrastructures where plenum-rated pathways are required. The 72-fiber count makes it well suited for high-density distribution frames, main distribution areas (MDAs), and horizontal or vertical backbone segments. It is sold as a single unit (EA) and is categorized under fiber and patch cable assemblies.

Key Features

• OM3 multimode fiber supports 10GbE and high-bandwidth backbone applications
• 72-fiber count for high-density cabling runs
• Plenum-rated construction suitable for air-handling spaces and plenum ceilings
• Tight-buffered design for indoor structured cabling installations
• CPE-designated for customer premises environments

Compatibility

Designed as an OEM-style indoor plenum fiber optic cable for use in commercial structured cabling systems requiring OM3 multimode 72-fiber backbone or distribution runs.

Installation Notes

Installation should be performed by a qualified low-voltage or fiber optic cabling technician in accordance with applicable building and fire codes, including NFPA 70 (NEC) Article 770 governing optical fiber cabling. Ensure the pathway is rated for plenum use before routing through air-handling spaces. Avoid sharp bends below the cable minimum bend radius and do not exceed rated pulling tension during installation. De-energize any adjacent powered infrastructure and follow site safety protocols before beginning work.
