The GYFTY/GYFTZY cable is constructed by wrapping 250 m of optical fiber into loose sleeves made of high-modulus materials, which are filled with waterproof compounds.At the center of the cable core is a phosphatized steel wire (FRP non-metallic reinforcing core). The loose sleeve (and filling rope) is twisted around the central reinforcing core to form a compact and round cable core. The gaps in the cable core are filled with water-blocking filler.A layer of polyethylene sheath (flame retardant sheath) is pressed on the core to form cable.
