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 covered with a thin PE inner jacket. After the steel tape is armored over the inner jacket, the cable is completed with a LSZH outer jacket.
