Belden Inc. FI3B006RB Fiber Optic Cable OM3 6F Ofnr

Product Description

The BELDEN INC. FI3B006RB is an indoor riser-rated fiber optic cable built to OM3 multimode specifications with a 6-fiber count. OM3 glass supports high-bandwidth applications including 10 Gigabit Ethernet and is optimized for laser-based transmission. The OFNR (Optical Fiber Nonconductive Riser) rating qualifies this cable for installation in building riser pathways between floors, meeting fire-spread resistance requirements under the NEC. It is sold as a single unit and is handled by licensed low-voltage and data/communications installers in commercial and industrial environments.

This cable is suited for structured cabling backbone runs, data center interconnects, and riser pathway installations in commercial buildings. The 6-fiber count makes it appropriate for moderate-density runs where a compact form factor and manageable cable diameter are priorities. Typical install scenarios include telecommunications rooms, equipment rooms, and floor-to-floor backbone segments in multi-story facilities.

Key Features

• OM3 multimode fiber supports 10 Gigabit Ethernet and laser-optimized transmission
• 6-fiber count in a compact riser cable format
• OFNR rating meets NEC requirements for riser-rated installations between building floors
• Nonconductive construction eliminates the need for grounding in most install scenarios
• Sold as individual unit (EA), one cable per order line

Compatibility

Designed as an OEM-style riser fiber optic cable suitable for use in structured cabling systems requiring OM3 multimode performance with a 6-fiber OFNR-rated backbone cable.

Installation Notes

Installation should be performed by a licensed low-voltage or communications cabling technician familiar with NEC Article 770 requirements for optical fiber cables. De-energize any adjacent electrical systems in the pathway before pulling cable through riser sleeves or conduit. Do not exceed the cable minimum bend radius during routing, as exceeding it can damage fiber strands and degrade signal performance. End terminations should be made with appropriate fiber connectors and tested with an optical loss test set per TIA-568 standards.
