Description
Central Tube Type Lightweight Armored Optical Cable is a durable and lightweight solution designed for outdoor applications requiring moisture resistance, mechanical strength, and ease of installation. The cable features colored optical fibers housed in a loose tube made of high-modulus, hydrolysis-resistant material. This loose tube is filled with thixotropic water-blocking gel to protect the fibers and enhance water resistance.
A layer of double-sided coated steel tape is longitudinally wrapped around the loose tube, with additional water-blocking gel applied between the steel tape and the tube, ensuring compactness and robust longitudinal water resistance. Two parallel steel wires provide enhanced tensile strength and stability, while a polyethylene sheath is extruded to protect the cable from environmental factors.
