Fibers are positioned in a central tube made of high-modulus plastic and filled with tube gel. The tube is armored with aramid yarns and water blocking yarns. Then the corruagted steel tape (CST ) is enhanced around the tube. Finally a LSZH jacket is extruded.
Equipped with the most advanced fiber drawing towers, high-speed proof testers,and other optical and mechanical testing facilities, CROFC is capable of producing 15 million core kilometres fibers and cables with superior performance.
