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.
The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the metallic strength member to form the cable core filled with water blocking compound. Then the steel tape (CST) is longitudinally armored over the cable core and a PE inner jacket is extruded. Finally the cable is completed with a blue flame-retardant PVC jacket.
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.
