Belden Inc. FDSH0125D OS2 Singlemode Riser Fiber Cable

Product Description

The BELDEN INC. FDSH0125D is an OS2 singlemode optical fiber cable rated for riser (OFCR) installations. It contains 12 individual fiber strands in a dry-construction design with a black outer jacket. OS2 singlemode fiber supports long-distance, high-bandwidth data transmission with extremely low signal attenuation. The dry-core construction eliminates gel filling, reducing mess and prep time during termination. This cable is installed by licensed low-voltage technicians, electricians, and structured-cabling contractors in commercial and industrial environments where backbone fiber runs are required.

This cable is suited for indoor riser pathways such as vertical runs between floors in commercial buildings, data centers, and campus backbone installations. The OFCR rating qualifies it for use in riser spaces as defined by the National Electrical Code. The 12-fiber count supports multi-circuit runs in a single cable pull, making it practical for backbone distribution frames and equipment room terminations. It is sold by the unit as indicated by the UOM designation.

Key Features

• OS2 singlemode fiber for long-distance, low-attenuation optical transmission
• 12-fiber count in a single cable for efficient backbone pulls
• OFCR riser rating meets NEC requirements for vertical shaft installations
• Dry-core construction eliminates gel, simplifying field termination and splicing
• Black outer jacket for standard indoor fiber identification

Compatibility

Designed as an OEM-style riser-rated singlemode fiber cable for use in structured cabling systems requiring OS2 12-fiber indoor backbone runs.

Installation Notes

Installation should be performed by qualified low-voltage or fiber-optic technicians following NEC riser-fill and bend-radius requirements. De-energize any associated active equipment before terminating or splicing fiber endpoints. Use appropriate fiber-cleaving and fusion-splicing or mechanical-splicing tools rated for OS2 singlemode fiber. Observe the cable's minimum bend radius throughout the pull to avoid microbend losses.
