Belden Inc. TU3LF002RN2N OM3 2-fiber Ofnr Riser Cable

Product Description

The BELDEN INC. TU3LF002RN2N is a tight-buffered multimode OM3 2-fiber indoor optical fiber cable rated OFNR for riser applications. OM3 multimode fiber supports high-bandwidth data transmission at 850 nm, making it a standard choice for structured cabling in commercial and industrial environments. The OFNR (Optical Fiber Nonconductive Riser) rating qualifies this cable for vertical runs between floors in accordance with NEC riser requirements. Licensed low-voltage and communications contractors install this cable in data centers, telecom rooms, and inter-floor backbone runs.

This cable is suited for indoor riser installations where a compact 2-fiber count is required. Typical applications include backbone runs between telecom closets, horizontal distribution within a floor, and short-haul data links in commercial buildings. The tight-buffered construction provides direct termination capability without additional fan-out kits, simplifying field termination. It is appropriate for both new construction and retrofit structured cabling projects where OM3 performance and riser-rated compliance are required.

Key Features

• OM3 multimode fiber supports 10 Gigabit Ethernet and high-bandwidth applications at 850 nm
• OFNR riser rating meets NEC requirements for vertical cable runs between building floors
• 2-fiber count in a compact form factor suited for low-density backbone and distribution links
• Tight-buffered construction allows direct field termination without fan-out hardware
• Nonconductive design eliminates grounding requirements and reduces installation complexity

Compatibility

Designed as an OEM-style optical fiber cable for indoor riser-rated structured cabling installations requiring OM3 multimode performance in a 2-fiber configuration.

Installation Notes

Installation should be performed by a licensed low-voltage or communications contractor familiar with TIA-568 structured cabling standards and NEC Article 770 requirements for optical fiber riser cables. Power down active network equipment before terminating or splicing fiber ends. Observe the cable minimum bend radius during pulling and routing to avoid microbend losses. Do not exceed the cable rated pulling tension during installation through conduit or cable tray.
