The BlueStorm double-armored fiber cable is a GYXTW-type outdoor optical cable built around a central loose tube, suitable for duct and aerial installation. This variant is a 4-core single-mode cable on a 1 km drum with a 7.0 mm outer diameter. A jelly-filled central loose tube protects and water-blocks the fibers, while copolymer-coated steel tape and two parallel steel wires provide armor and tensile strength beneath a PE outer sheath. The double-jacket construction adds moisture and crush resistance, and the cable's low dispersion and attenuation suit it to long-distance links.
