Belden Inc. FD3L012RD OM3 Loose Tube Fiber Cable 12 Fiber

Product Description

The BELDEN INC. FD3L012RD is an FX series indoor/outdoor loose tube fiber optic cable rated for OM3 multimode transmission with a 12-fiber count. This cable is engineered for structured cabling installations that transition between interior building runs and exterior pathways without requiring a separate transition splice or junction. The loose tube construction protects the fiber strands from moisture ingress, mechanical stress, and temperature fluctuations. It is suited for high-bandwidth backbone applications including 10 Gigabit Ethernet and other OM3-compatible transmission protocols. Licensed low-voltage contractors and network infrastructure technicians are the primary installers of this product.

The FD3L012RD is designed for use in commercial and institutional environments where a single continuous cable run must pass through both conditioned indoor spaces and exposed outdoor or plenum-adjacent pathways. Typical applications include campus backbone runs, riser installations, and building-entry segments where an indoor/outdoor dual-rated construction eliminates the need for a separate outdoor-rated transition cable. The 12-fiber configuration supports multiple parallel links within a single jacket, making it practical for multi-drop or aggregated backbone scenarios.

Key Features

• OM3 multimode fiber supports 10 Gigabit Ethernet and high-bandwidth backbone applications
• Indoor/outdoor dual rating eliminates the need for a transition splice at building entry
• Loose tube construction isolates fiber strands from mechanical stress and moisture
• 12-fiber count provides multiple parallel paths in a single cable run
• FX series construction designed for structured cabling backbone deployments

Compatibility

Designed as an OEM-style indoor/outdoor loose tube fiber optic cable compatible with standard OM3 multimode fiber termination hardware, patch panels, and splice enclosures accepting 12-fiber loose tube assemblies.

Installation Notes

Installation should be performed by a licensed low-voltage or data cabling contractor familiar with TIA-568 and applicable local building codes. De-energize any adjacent electrical systems and verify conduit fill limits before pulling the cable. Avoid exceeding the cable minimum bend radius during installation, as kinking or over-bending can permanently damage fiber strands. All outdoor-exposed jacket sections should be properly sealed at entry points to prevent moisture migration into the building.
