he structure of GYTA cable involves inserting fiber ribbons into loose tubes made of high-modulus material. The loose tubes are filled with a waterproof compound. The core''''s center is a metallic strength member. For certain fiber counts, an additional layer of polyethylene (PE) is extruded over this metallic member. The loose tubes (and filler rods) are stranded around the central strength member into a compact circular core. Interstices within the core are filled with a water-blocking material. A longitudinally applied plastic coated aluminum tape (APL) is applied before a polyethylene (PE) jacket is extruded to form the complete cable.
