The structure of GDTA53 type optoelectronic hybrid cable is to embed single-mode or multi-mode optical fibers into a loose sleeve made of high modulus polyester material, and fill the sleeve with waterproof compound. The center of the cable core is a metal reinforced core, and for some fiber optic cables with a certain number of cores, a layer of polyethylene needs to be extruded outside the metal reinforced core. The loose tube and insulated copper wire of the required specifications are twisted around the central reinforcing core to form a compact circular cable core, and the gaps inside the cable core are filled with water-resistant fillers. After longitudinally wrapping the coated aluminum strip, a layer of polyethylene inner sheath is extruded, and the outer layer is made of double-sided chrome plated coated steel strip (PSP) rolled longitudinally wrapped and extruded with polyethylene outer sheath to form a cable.
