Belden Inc. TU3LG024RS2N OM3 24-fiber Riser Optical Cable

Product Description

The BELDEN INC. TU3LG024RS2N is a multimode OM3 24-fiber indoor optical fiber cable rated for riser (OFCR) installations. Constructed with a tight-buffered, multi-fiber architecture, this cable is designed for high-bandwidth backbone and horizontal runs inside commercial and industrial buildings. The OM3 laser-optimized multimode designation supports high-speed data transmission at 10 Gigabit Ethernet and beyond over standard multimode transceiver equipment. Licensed electricians, low-voltage contractors, and structured cabling technicians are the primary installers of this cable type.

This cable is suited for indoor riser pathways between floors in commercial office buildings, data centers, healthcare facilities, and campus environments. The riser flame rating (OFCR) qualifies it for use in vertical runs between floors where it must pass through fire-rated floor openings, meeting the requirements for riser-rated fiber pathways. It is not rated for plenum spaces. Applications include backbone fiber runs, patch panel terminations, and equipment room interconnects where a 24-fiber count provides high port density in a single cable pull.

Key Features

• OM3 laser-optimized multimode fiber supports 10GbE and higher data rates
• 24-fiber count delivers high port density in a single riser pull
• Tight-buffered construction simplifies field termination and connector installation
• OFCR riser flame rating meets NEC Article 770 requirements for vertical runs between floors
• Indoor-rated design for use in protected building pathways

Compatibility

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

Installation Notes

Installation should be performed by a licensed low-voltage contractor or certified fiber optic technician in accordance with NEC Article 770 and applicable local codes. De-energize all active equipment connected to the fiber pathway before beginning work. Do not exceed the cable's minimum bend radius during pulling, routing, or storage. Proper strain relief and fire-stopping at rated penetrations are required at all floor-to-floor riser openings.
