GYDTA (metal strengthening member, loose tube stranded and filled with optical fiber ribbon, aluminum-polyethylene bonded sheathed outdoor optical fiber cable for communication) The structure of the optical cable is to sheath the single-mode optical fiber ribbon with 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 certain number of cores, the metal reinforced core can be a steel strand, which can be extruded with a layer of polyethylene (PE). The loose tube (and the filling rope) is twisted around the central reinforcing core to form a compact and circular cable core. The gaps in the cable core are filled with water-blocking compounds and then coated with a plastic aluminum tape longitudinally wrapped with a polyethylene sheath.

Features:
●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
●Optical cable has small diameter, high fiber density and light weight
●Smooth outer sheath enables the optical cable to have a smaller coefficient of friction during installation
●PE sheath has good resistance to solar radiation
●The following measures are taken to ensure the waterproof performance of the optical cable: the loose tube is filled with special waterproof compound; the outside of the cable core is filled with water-swellable water-blocking cable paste; the plastic-coated aluminum tape moisture-proof layer
