Belden FDSD012R9 12-strand Singlemode Riser Fiber Cable

Product Description

The Belden Inc. FDSD012R9 is a 12-strand singlemode riser-rated fiber optic cable designed for indoor vertical and backbone runs. It supports both simplex and duplex signal transmission in a tight, organized form factor suited to structured cabling installations. The riser rating qualifies it for use in building risers and vertical shafts where flame spread must be controlled per applicable fire codes. Licensed low-voltage and fiber optic technicians are the primary installers of this cable in commercial and institutional buildings.

This cable is used in singlemode fiber backbone applications where long-distance, low-loss transmission is required between floors or between telecommunications rooms and equipment rooms. The in-out configuration supports both entry-point and distribution roles within a building cabling system. It is well-suited for enterprise networks, campus backbones, and structured cabling projects that require riser-rated runs per TIA-568 guidelines.

Key Features

• 12-strand singlemode fiber construction for high-capacity backbone runs
• Riser-rated jacket for compliant installation in vertical building shafts
• In-out design supports both riser distribution and entry-point applications
• Black jacket for easy identification in singlemode riser installations
• Sold individually as a single unit (EA)

Compatibility

Designed as an OEM-style singlemode riser fiber cable for use in standard indoor vertical backbone and interfloor cabling systems where riser-rated, 12-strand singlemode fiber is specified.

Installation Notes

Installation should be performed by a licensed low-voltage or fiber optic technician familiar with TIA-568 structured cabling standards and applicable local fire codes governing riser-rated pathways. De-energize any active equipment connected to the fiber run before terminating or splicing. Follow building code requirements for firestop sealing wherever the cable passes through floor penetrations. Avoid exceeding the minimum bend radius of the cable during routing and pulling to prevent signal degradation.
