Belden Inc. FD1D024R9 OM1 24-fiber Ofnr Distribution Cable

Product Description

The BELDEN INC. FD1D024R9 is an indoor fiber optic distribution cable built around OM1 multimode fiber with a 24-fiber count and an OFNR (Optical Fiber Nonconductive Riser) flame rating. This cable is designed for structured cabling runs inside buildings where riser-rated pathways are required by code. The distribution-style construction keeps the overall diameter compact, making it practical for routing through conduit, cable trays, and riser shafts. Network installers and low-voltage contractors use this cable to connect patch panels, switches, and fiber distribution hubs across floors or between equipment rooms.

This cable is suited for horizontal and vertical indoor backbone runs in commercial, institutional, and light industrial facilities. Its OFNR rating makes it appropriate for use in riser applications as defined by the National Electrical Code without the need for innerduct in most jurisdictions. The 24-fiber count supports dense deployments where multiple network segments or structured cabling zones are consolidated into a single cable run, reducing pathway congestion and installation time.

Key Features

• OM1 multimode fiber supports legacy and active multimode transceivers in installed base environments
• 24-fiber count allows high-density routing in a single cable pathway
• OFNR flame rating meets NEC riser requirements for indoor vertical installations
• Distribution-style design provides a compact, manageable cable form factor for conduit and tray routing
• Indoor-rated construction optimized for climate-controlled building environments

Compatibility

Designed as an OEM-style indoor distribution fiber cable for riser-rated structured cabling installations using OM1 multimode fiber infrastructure.

Installation Notes

Installation should be performed by a licensed low-voltage contractor or structured cabling technician familiar with NEC Article 770 requirements for optical fiber riser cables. Verify that all conduit fill ratios and bend radius minimums appropriate to the cable diameter are observed during pulling. Do not exceed the cable's rated minimum bend radius, and avoid sharp kinks or crush points during routing. Terminate and test fiber ends with appropriate fusion splicing or mechanical connector equipment before commissioning the link.
