Belden Inc. FI3D036RK OM3 36-fiber Ofnr Cable

Product Description

The BELDEN INC. FI3D036RK is an indoor OM3 multimode fiber optic cable assembly rated OFNR (Optical Fiber Nonconductive Riser). Designed for structured cabling installations inside commercial and institutional buildings, it carries 36 individual fibers within a riser-rated jacket that meets fire propagation requirements for vertical runs between floors. OM3 multimode glass supports high-bandwidth applications including 10 Gigabit Ethernet and fiber channel links at distances suited to intra-building backbone and horizontal distribution runs. Network technicians and low-voltage cabling contractors are the primary installers of this assembly.

This cable assembly is suited for indoor riser pathway installations in commercial office buildings, data centers, healthcare facilities, and educational campuses. The 36-fiber count supports high-density backbone segments where multiple network or storage links must be consolidated into a single cable run. OFNR-rated jacket material qualifies the assembly for installation in riser spaces without conduit where permitted by local code, making it practical for multi-floor structured cabling projects.

Key Features

• OM3 multimode fiber supports 10 Gigabit Ethernet and high-bandwidth applications
• 36-fiber count enables high-density backbone and distribution runs in a single cable
• OFNR riser-rated jacket meets fire propagation requirements for vertical indoor runs
• Indoor-rated construction designed for protected building environments
• Single-unit packaging for straightforward project quantity management

Compatibility

Designed as an OEM-style indoor riser fiber optic cable assembly for use with OM3 multimode fiber optic termination hardware, patch panels, and enclosures in structured cabling systems.

Installation Notes

Installation should be performed by a licensed low-voltage or communications cabling contractor familiar with TIA-568 structured cabling standards. De-energize any active equipment in the pathway before pulling cable to avoid interference or damage. Observe the cable's minimum bend radius and maximum pulling tension throughout the run. Riser installations must comply with applicable sections of the National Electrical Code (NEC) Article 770 governing optical fiber cables.
