Belden Inc. TU3LG008RS2N OM3 8-fiber Riser Optical Cable

Product Description

The BELDEN INC. TU3LG008RS2N is an OM3-rated multimode optical fiber cable designed for indoor structured cabling installations. Built with 8 fibers in a compact polyethylene construction, this riser-rated cable is suited for vertical runs between floors in commercial and institutional buildings. OM3 multimode fiber supports 10-Gigabit Ethernet and other high-bandwidth protocols over standard multimode transceivers. Licensed low-voltage and datacom contractors specify this cable for backbone and riser segment work where a fire-rated, tight construction is required.

This cable is intended for indoor riser (OFCR-rated) applications in commercial buildings, data centers, and campus environments. It is well-suited for vertical backbone runs connecting telecom rooms and equipment rooms. The 8-fiber count supports moderate-density riser segments where a single cable must serve multiple paths without requiring a larger trunk. OFCR fire-rating makes it appropriate for installation in building risers and vertical shafts under applicable codes.

Key Features

• OM3 multimode fiber supports 10GbE and high-bandwidth applications
• 8-fiber count in a single cable for moderate-density riser backbone runs
• OFCR (Optical Fiber Conductive Riser) fire rating for vertical indoor installation
• Compact indoor construction suitable for conduit and innerduct routing
• Designed for use with standard multimode LC, SC, and ST connectors

Compatibility

Designed as an OEM-style indoor riser optical cable for use in commercial structured cabling systems requiring OM3 multimode fiber with an OFCR fire rating.

Installation Notes

Installation should be performed by a licensed low-voltage or datacom contractor familiar with TIA-568 and NFPA 70 (NEC) Article 770 requirements for optical fiber cables in riser spaces. De-energize any nearby electrical equipment before pulling cable through shared pathways. Do not exceed the cable minimum bend radius during installation, and avoid exceeding the rated tensile load during pull-through. Terminate with appropriate OM3-rated connectors and test with a multimode OTDR or optical loss test set per project specifications.
