Belden Inc. FD3L024RD OM3 24-fiber Loose Tube Riser Cable

Product Description

The BELDEN INC. FD3L024RD is a loose tube, OM3 multimode fiber optic cable configured with 24 fibers and rated for indoor riser (OFNR) installations. Loose tube construction protects individual fibers from mechanical stress and moisture migration, making it well suited for vertical runs through building risers and conduit systems. The OM3 designation indicates a 50/125-micron multimode fiber optimized for laser-based transmission, commonly used with 10 Gigabit Ethernet and other high-bandwidth applications. Low-voltage and data cabling contractors install this cable during new construction or infrastructure upgrades.

This cable is designed for indoor riser pathway installations where a flame-retardant, non-conductive rating is required by code. Typical applications include backbone cabling between telecommunications rooms, riser runs between floors in commercial and institutional buildings, and structured cabling infrastructure supporting high-speed network equipment. The 24-fiber count supports enterprise-scale deployments where multiple network segments or high port-count patching is required.

Key Features

• OM3 50/125-micron multimode fiber supports 10 Gigabit Ethernet and laser-optimized transmission
• Loose tube construction isolates fibers from tensile and crush stress during installation
• OFNR (Optical Fiber Nonconductive Riser) rating meets NEC requirements for riser-rated indoor pathways
• 24-fiber configuration supports high-density backbone and riser cabling infrastructure
• Non-conductive design eliminates the need for additional bonding or grounding at cable ends

Compatibility

Designed as an OEM-style riser-rated loose tube fiber optic cable suitable for indoor vertical and backbone runs in commercial structured cabling systems meeting OFNR pathway requirements.

Installation Notes

Installation should be performed by a qualified low-voltage or data cabling contractor familiar with TIA-568 structured cabling standards and applicable NEC riser pathway requirements. Observe the cable's minimum bend radius and maximum tensile load ratings during pulls to avoid microbending or fiber damage. Power down any active network equipment connected to the fiber pathway before splicing or terminating. Do not exceed the cable's rated vertical rise span without intermediate support as required by the NEC.
