Description
Central Tube Type Non-armored Optical Cable is a high-performance solution designed for outdoor applications requiring reliable water resistance, mechanical stability, and lightweight construction. Colored optical fibers are securely housed in a loose tube made of high-modulus, hydrolysis-resistant material, which is filled with thixotropic water-blocking gel for superior fiber protection.
To enhance water resistance, the loose tube is externally coated with water-blocking material, ensuring robust longitudinal water-blocking performance. Two parallel steel wires are positioned on both sides to provide tensile strength and structural stability. The cable is finished with a polyethylene sheath, offering excellent protection against environmental factors.
