Belden Inc. FD3L144RD OM3 144-fiber Riser Fiber Optic Cable

Product Description

The BELDEN INC. FD3L144RD is a loose-tube, 144-fiber OM3 multimode fiber optic cable rated for indoor riser (OFNR) installations. Loose-tube construction protects individual fibers from mechanical stress and moisture migration, making it well suited for vertical backbone runs between floors. OM3 multimode fiber supports high-bandwidth applications including 10 Gigabit, 40 Gigabit, and 100 Gigabit Ethernet over appropriate distances. Licensed electricians, low-voltage contractors, and structured cabling technicians are the primary installers of this product in commercial and institutional buildings.

This cable is intended for indoor riser-rated pathways in commercial, institutional, and multi-story residential buildings. It is used in telecommunications rooms, main distribution frames, and intermediate distribution frames where a high-fiber-count backbone is required. The 144-fiber count makes it appropriate for large campus or building backbone segments where significant port density is needed across a single cable run. OFNR rating qualifies it for installation in vertical shaft and riser spaces per building and fire codes.

Key Features

• 144-fiber count supports high-density backbone infrastructure in a single cable
• OM3 multimode fiber grade enables 10GbE, 40GbE, and 100GbE transmission
• Loose-tube construction provides mechanical protection and separation of fiber bundles
• OFNR (Optical Fiber Nonconductive Riser) rating for use in riser and vertical shaft spaces
• Indoor-rated jacket suitable for protected interior environments

Compatibility

Designed as an OEM-style riser fiber optic cable for use with standard OM3 multimode connectors, patch panels, and fiber distribution frames in indoor structured cabling systems.

Installation Notes

Installation should be performed by a qualified low-voltage contractor or licensed electrician familiar with TIA-568 structured cabling standards and applicable local fire codes. Power down any active equipment connected to the fiber pathway before terminating or splicing. Observe the cable minimum bend radius during pulling and routing to avoid microbend-induced signal loss. Do not use this cable in outdoor, direct-burial, or plenum-rated spaces where a different jacket rating is required.
