Our CST (Corrugated Steel Tape) fiber optic cable is engineered for exceptional durability and performance in the harshest environments. Featuring a central unitube housing 4-24 fibers, it is surrounded by a water-blocking fiberglass yarn and a corrugated steel tape strength member. This robust construction provides superior crush, tensile, and rodent resistance.
To further enhance protection, the outer sheath can be customized with PE, LSZH, or flame-retardant materials to meet specific application requirements. Whether you’re facing extreme weather conditions or challenging installation terrains, our CST cable is designed to withstand it all.
Key Features
- Unmatched Durability: Corrugated steel tape and fiberglass yarn for superior crush, tensile, and rodent resistance.
- Versatile Protection: Customizable outer sheath options for diverse environments.
- Flexible Design: Available in a wide range of fiber counts (4, 12, 24, 48, 96, 144, 288) to suit your project needs.
- Customization Options: Choose from various fiber and jacket colors to match your specific requirements.
Our CST fiber optic cable is the ideal solution for demanding applications where reliability and performance are paramount.
Applications
- Underground and duct installations
