Belden Inc. FD1D024RJ OM1 24-fiber Ofnr Distribution Cable

Product Description

The BELDEN INC. FD1D024RJ is an indoor distribution-style fiber optic cable rated for OM1 multimode transmission with a 24-fiber count and an OFNR (Optical Fiber Nonconductive Riser) flame rating. Designed for structured cabling installations inside commercial and industrial buildings, it supports backbone and horizontal runs where riser-rated cable is required by code. The distribution construction keeps the cable compact and organized for high-density termination environments. Network technicians and low-voltage cabling contractors are the primary installers of this cable type.

This cable is suited for intrabuilding fiber runs between floors or across a facility where riser-rated pathways are required. The OM1 multimode specification supports legacy multimode applications at 62.5-micron core diameter. With 24 fibers in a single jacket, it works well for moderate- to high-count backbone segments in office buildings, schools, healthcare facilities, and light industrial environments. It is sold as a single unit (EA) per the supplier unit of measure.

Key Features

• OFNR flame rating meets National Electrical Code riser-pathway requirements for intrabuilding vertical runs
• OM1 multimode fiber supports existing legacy multimode network infrastructure
• 24-fiber count in a single cable for efficient high-density backbone routing
• Distribution-style construction provides a compact form factor suited for direct termination or breakout applications
• Indoor-rated design for structured cabling in commercial and institutional buildings

Compatibility

Designed as an OEM-style replacement or new-installation fiber optic cable for indoor riser-rated structured cabling systems requiring OM1 multimode, 24-fiber distribution cable.

Installation Notes

Installation should be performed by a licensed low-voltage or network cabling contractor in accordance with NEC Article 770 requirements for optical fiber riser cables. De-energize any adjacent electrical systems before pulling cable through shared pathways. Observe the manufacturer-rated minimum bend radius during pulling and dressing to avoid fiber attenuation or damage. Terminate fibers using appropriate fusion splicing or mechanical connector tooling rated for 62.5-micron OM1 fiber.
