Colored optical fibers are placed into loose tubes made of high-modulus, hydrolysis-resistant material, which are filled with thixotropic water- blocking paste. A layer of fine round steel wires is stranded around the loose tubes to form a compact, circular cable core, with water-blocking fillers packed into the gaps within the core. After longitudinally wrapping with plastic-coated aluminum tape, a polyethylene inner sheath is extruded. Then, after being armored with a single fine round steel wire, a polyethylene outer sheath is finally extruded to complete the cable.
