Description

The BELDEN INC. FI1D024R9 is an indoor distribution-style fiber optic cable rated OFNR (Optical Fiber Nonconductive Riser) and built around an OM1 multimode fiber core. With 24 individual fibers, this cable is designed for structured cabling installations inside commercial and industrial buildings where a riser fire rating is required by code. Electricians and low-voltage cabling technicians install this type of cable in vertical runs between floors, in conduit, and in cable trays where a plenum rating is not required but riser compliance is mandated.

This cable suits backbone and horizontal distribution runs in commercial buildings, data centers, and campus environments where OM1 multimode performance meets the bandwidth demands of the application. The OFNR rating makes it appropriate for use in vertical shaft and riser applications as defined by the National Electrical Code. It is sold per individual unit and is intended for professional installation by licensed low-voltage or electrical contractors familiar with fiber optic handling and termination practices.

Key Features

OM1 multimode fiber supports standard multimode transmission applications
24-fiber count provides high-density connectivity in a single cable run
OFNR rating meets NEC riser fire resistance requirements for vertical indoor runs
Indoor distribution construction suited for conduit, cable tray, and riser shaft routing
Sold as a single unit (EA) for precise quantity ordering

Compatibility

Designed as an OEM-style distribution fiber optic cable for indoor riser applications requiring OM1 multimode, 24-fiber OFNR-rated cable in commercial and industrial structured cabling systems.

Installation Notes

Installation should be performed by a qualified low-voltage or licensed electrical contractor in accordance with NEC Article 770 governing optical fiber cables. De-energize any adjacent electrical systems and follow all building fire-stop requirements when penetrating floors or fire-rated assemblies. Observe the cable minimum bend radius and maximum pull tension during installation to avoid damaging the fiber. Do not exceed the rated pulling tension or use pulling grips that could crush or kink the cable jacket.
