Belden Inc. FSSL012ND 12-fiber Single-mode Outdoor Cable

Product Description

The BELDEN INC. FSSL012ND is a 12-fiber single-mode outdoor loose tube fiber optic cable designed for exterior plant and campus distribution applications. The loose tube construction protects individual fibers from environmental stress, moisture, and temperature fluctuation, making it well-suited for direct burial, conduit, or aerial installations. Licensed low-voltage and outside plant technicians install this cable type in backbone and feeder runs where long-distance, high-bandwidth transmission is required. The single-mode fiber design supports low-attenuation signal transmission over extended distances.

This cable is intended for outdoor use in commercial, industrial, and campus environments where the cable run is exposed to weather, UV, or physical stress. Typical applications include inter-building backbone runs, telecommunications infrastructure, data center campus links, and utility distribution networks. The loose tube design allows fibers to float freely within gel-filled or dry buffer tubes, isolating them from tensile and compressive loads applied to the cable jacket.

Key Features

• 12-fiber count in a single-mode loose tube configuration
• Outdoor-rated jacket suitable for direct burial, conduit, or aerial deployment
• Loose tube construction isolates fibers from mechanical and thermal stress
• Single-mode fiber supports high-bandwidth, long-distance transmission
• Sold as individual unit (EA), quantity per package: 1

Compatibility

Designed as an OEM-style outdoor fiber optic cable compatible with standard single-mode fiber termination hardware, splice enclosures, and distribution panels that accept loose tube 12-fiber cables.

Installation Notes

Installation should be performed by a qualified outside plant or low-voltage cabling technician familiar with fiber optic handling practices. Power down or de-energize any adjacent active systems before working in cable pathways. Follow TIA-568 and local building codes for bend radius, pulling tension, and conduit fill requirements. Never exceed the cable's rated minimum bend radius or maximum tensile load during installation, as exceeding these limits can permanently degrade fiber performance.
