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. The steel tape(CST) is longitudinally armored over the cable core, which is filled with water blocking compound. Finally a PE jacket is extruded.
