Part number definition GY——Communication room (field) outdoor optical cable T ——filled structure A ——Aluminum-polyethylene bonded sheath GYTA (metal strengthening member, loose tube stranded and filled, aluminum-polyethylene bonded sheathed outdoor optical fiber cable for communication) The structure of the optical cable is to sheath single-mode or multi-mode optical fiber into the inner filling made of high modulus plastic Waterproof compound in loose tube. The center of the cable core is a metal reinforced core. For some fiber optic cables, the metal reinforced core is also extruded with a layer of polyethylene (PE). The loose tube (and filling rope) is twisted around the central reinforcing core to form a compact and circular cable core, and the gaps in the cable core are filled with water blocking compounds. The aluminum-plastic composite tape is longitudinally wrapped and then extruded with a polyethylene sheath. ●Precise control of the excess length of the optical fiber ensures that the optical cable has good tensile performance and temperature characteristics ●PBT loose tube material has good hydrolysis resistance, and the tube is filled with special grease to protect the optical fiber ●PE sheath has good resistance to solar radiation ●Smooth outer sheath enables the optical cable to have a smaller coefficient of friction during installation ●The following measures are taken to ensure the waterproof performance of the optical cable: special waterproof compound is filled in the loose tube; completely filled with the cable core; aluminum-plastic composite with moisture-proof layer ●The side pressure index of aluminum belt is not as good as that of steel belt, but the moisture-proof and rust-proof effect is better than that of steel belt. GYTA has a long life when used in pipes.
