Optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with water blocking yarns. The tubes (and fillers) are stranded around the central strength member to form a cable core. The core is covered by water blocking tape and armored with steel tape. Stranded steel wires are applied as the messenger. Finally, a figure-8 PE outer sheath is extruded.
