GYTA53 (metal strengthening member, loose tube layer stranded filling type, aluminum-polyethylene bonded sheath, longitudinally wrapped corrugated steel tape armor, polyethylene sheathed outdoor optical cable for communication) The structure of the optical cable is a single-mode or multi-mode optical fiber jacket Into a loose tube made of high modulus plastic filled with waterproof compound. 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. Plastic-coated aluminum tape is longitudinally wrapped and then extruded with a layer of polyethylene inner sheath, double-sided plastic-coated steel tape is longitudinally wrapped and then extruded with a polyethylene sheath.
