Belden Inc. TU3LF004RN2N OM3 4-fiber Riser Cable

Product Description

The BELDEN INC. TU3LF004RN2N is a multimode OM3 4-fiber indoor riser-rated fiber optic cable designed for structured cabling installations in commercial and light industrial environments. OM3 multimode glass fiber supports high-bandwidth applications including 10 Gigabit Ethernet over standard distances. The riser (OFNR) flame rating makes this cable suitable for vertical runs between building floors without the need for conduit in most code-compliant installations. Licensed low-voltage contractors and network cabling technicians are the primary installers for this type of cable.

This cable is intended for indoor vertical backbone and horizontal distribution runs where a compact, 4-fiber count meets bandwidth and capacity requirements. The CPE (customer premises equipment) construction and OFNR rating suit office buildings, data centers, healthcare facilities, and educational campuses. It is sold per unit (EA) with a quantity of one per unit as supplied.

Key Features

• OM3 multimode fiber supports 10 Gigabit Ethernet and high-bandwidth data transmission
• 4-fiber count in a compact cable form factor for low-pair-count backbone and zone cabling
• OFNR (Optical Fiber Nonconductive Riser) flame rating for code-compliant vertical floor-to-floor runs
• CPE-rated construction for use in customer premises and indoor environments
• Indoor-optimized design reduces unnecessary bulk in tray, conduit, or cable management systems

Compatibility

Designed as an OEM-style replacement or new-installation fiber optic cable for indoor riser multimode OM3 structured cabling systems.

Installation Notes

Installation should be performed by a licensed low-voltage or network cabling contractor familiar with TIA-568 and NEC Article 770 requirements for optical fiber riser cable. De-energize and lock out any adjacent electrical systems before pulling cable through shared pathways or conduit. Avoid exceeding the cable minimum bend radius during pulls to prevent fiber damage. Terminate using appropriate OM3-rated connectors and test with an optical loss test set after installation.
