The GJFZY53-FR fire-resistant fiber cable is made of 250 m fiber into a loose sleeve made of a high modulus material filled with a waterproof compound. The center of the cable core is a non-metallic FRP core. For some fiber optic cables with core number, a layer of polyethylene (PE) should be extruded outside the non-metallic core. The loose casing (and filling rope) is twisted around the central reinforcement core to form a compact and round cable core. After longitudinal wrapping, a layer of flame retardant inner sheath is extruded. After longitudinal wrapping, a double-sided coated plastic steel strip (PSP) is extruded to form a cable with flame retardant outer sheath.
