Belden Inc. FD4D048RK OM4 48-fiber Ofnr Riser Cable

Product Description

The BELDEN INC. FD4D048RK is an indoor fiber optic distribution cable designed for high-density installations requiring reliable multimode transmission. Built to OM4 specifications, this 48-fiber riser-rated (OFNR) cable supports high-bandwidth applications in structured cabling environments. The OFNR rating qualifies it for vertical runs between floors in commercial and industrial buildings without the need for innerduct in most code-compliant installations. Licensed low-voltage and fiber optic technicians are the typical installers for this product type.

This cable is suited for backbone and distribution runs in commercial buildings, data centers, and campus environments where OM4 multimode performance is required. The 48-fiber count makes it appropriate for high-density patch panels, fiber distribution hubs, and main distribution frame connections. It is intended for indoor, riser-rated pathway applications only and is not rated for outdoor or direct-burial use.

Key Features

• OM4 multimode fiber classification supports high-bandwidth, short-reach applications
• 48-fiber count suited for high-density distribution and backbone runs
• OFNR riser rating meets NEC requirements for vertical shaft and riser installations
• Distribution-style construction provides a compact, manageable cable form factor for indoor routing
• Sold as a single unit (EA)

Compatibility

Designed as an OEM-style indoor distribution cable for use with OM4-compatible fiber optic patch panels, adapters, and connectors in riser-rated building pathways.

Installation Notes

Installation should be performed by a qualified low-voltage or fiber optic technician in accordance with NEC Article 770 requirements for optical fiber cables. De-energize any adjacent electrical systems and follow building management protocols before routing through riser shafts or conduit. Do not exceed the cable minimum bend radius during pulling or termination. Proper fiber handling tools, including strippers and cleavers rated for the fiber count, should be used during termination.
