Belden Inc. TU3LG012RH2N OM3 12-fiber Plenum Cable

Product Description

The BELDEN INC. TU3LG012RH2N is a multimode OM3 12-fiber indoor plenum-rated fiber optic cable designed for structured cabling installations in commercial and institutional buildings. It carries 12 optical fibers in an OM3 laser-optimized multimode configuration, making it suitable for high-speed data transmission over 10 Gigabit and 40 Gigabit Ethernet networks. The plenum-rated jacket (CPE, OFCR) meets the requirements for installation in air-handling spaces where fire and smoke safety compliance is mandatory. Licensed electricians and low-voltage cabling contractors are the primary installers of this product.

This cable is used in horizontal and backbone runs within commercial office buildings, data centers, healthcare facilities, and campus environments. Its OM3 multimode designation supports high-bandwidth applications including 10GbE, 40GbE, and fiber channel links over standard multimode distances. The 12-fiber count suits medium-density backbone runs or consolidation point connections where a compact, manageable cable assembly is preferred over larger fiber counts.

Key Features

• OM3 laser-optimized multimode fibers support 10GbE and 40GbE transmission
• 12-fiber configuration for medium-density backbone and horizontal cabling
• Plenum-rated jacket suitable for installation in air-handling plenums and ducts
• OFCR (Optical Fiber Conductive Riser) rating for vertical and riser runs
• Designed for use as a patch cable or short interconnect segment in structured cabling systems

Compatibility

Designed as an OEM-style replacement or standard-fit option for indoor plenum multimode fiber optic patch cable applications in structured cabling systems requiring OM3 12-fiber assemblies.

Installation Notes

Installation should be performed by a licensed low-voltage cabling contractor or electrician familiar with TIA-568 and NEC Article 770 requirements for optical fiber cabling. De-energize any active equipment connected to the fiber path before making or breaking connections. Observe minimum bend radius specifications during routing to avoid signal degradation. Do not exceed the cable's rated tensile load during pulling operations in conduit or cable tray.
