Belden Inc. TU3LG012RT2N OM3 12-fiber Plenum Cable

Product Description

The BELDEN INC. TU3LG012RT2N is a multimode OM3 12-fiber indoor plenum-rated fiber optic cable designed for high-density structured cabling installations. It carries 12 individual optical fibers in an OM3 50/125-micron configuration suited for high-bandwidth data transmission over short to moderate distances. The plenum jacket rating (CMP/OFCR) allows installation in air-handling spaces without the need for conduit, meeting fire safety requirements for commercial building applications. Licensed low-voltage contractors and structured cabling installers are the primary trades that work with this cable.

This cable is used in commercial and enterprise environments where OM3 multimode fiber is specified for backbone or horizontal runs. Typical applications include data centers, server rooms, telecommunications rooms, and campus riser pathways. The 12-fiber count supports aggregated links or multiple individual channel assignments within a single cable run. Its indoor plenum construction makes it well suited for above-ceiling or open plenum pathway installations where local fire codes require CMP-rated materials.

Key Features

• OM3 multimode fiber supports 10GbE and higher transmission standards over qualified distances
• 12-fiber construction enables high-density routing in a compact cable form factor
• Plenum-rated jacket (OFCR) meets fire code requirements for air-handling space installation without conduit
• Indoor-rated design for structured cabling backbone and horizontal pathway applications
• Sold as individual unit (EA) for project-specific procurement flexibility

Compatibility

Designed as an OEM-style structured cabling solution compatible with standard OM3 multimode fiber termination hardware, patch panels, and fiber optic connectors used in commercial low-voltage cabling systems.

Installation Notes

Installation should be performed by a licensed low-voltage or structured cabling contractor in accordance with ANSI/TIA-568 standards and applicable local fire and building codes. De-energize any adjacent active equipment before pulling cable through pathways or terminating fibers. Observe manufacturer minimum bend radius requirements during pulling and routing to prevent fiber damage. Plenum-rated cable installed in air-handling spaces must comply with NEC Article 770 and local authority having jurisdiction requirements.
