Non-metallic lamination stranded outdoor optical cable(GYFTY)
GYFTY fiber optic cables [1] are structured with 250μm fibers placed in loose tubes made of a high modulus material, which are filled with a waterproof compound. The center of the cable core is a glass fiber reinforced plastic (FRP). The loose sleeve (and filler rope) are twisted around the central strengthening core to form a compact and circular cable core. The gaps in the cable core are filled with water-resistant filler. The cable core is extruded with a layer of polyethylene inner sheath to form the cable.
