The fiber, either single-mode or multimode type, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of the core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. A corrugated steel tape armor (CST) is longitudinally applied over the cable core. The cable core is filled with a filling compound to protect it from water. The cable is completed with a Polyethylene (PE) sheath.
