Fibres are housed in a loose tube that is made of high-modulus plastic and filled with tube gel. The tubes are armored with a corrugated steel tape (CST) logitudinally. Between the steel tape and the loose tube water-blocking material is applied to keep the cable compact and water-tight. Two parallel steel wires are embeded in the LSZH 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.
