Sheathing Materials and Technologies

Fiber optic cable sheaths are typically made from PVC, polyethylene, polyurethane, or specialized polymers. Advanced extrusion technologies allow precise control over jacket thickness, centricity, and mechanical properties. Some sheaths include armoring or strength members for additional protection against environmental and mechanical stresses .

Applications

• Indoor cables: Flame-retardant jackets for plenum or riser installations.
• Outdoor cables: UV-resistant, water-blocking, and armored sheaths for aerial, duct, or direct-buried deployment.
• Harsh environments: High-temperature, chemical-resistant, and abrasion-resistant polymer sheaths for industrial or sensing applications . These manufacturers provide both standard and customized sheathing solutions, supporting global supply chains and ensuring compatibility with various fiber optic cable production lines.
