Product description

GYTZA53 (metal strengthening member, loose tube layer stranded filling type, aluminum-polyethylene bonded sheath, longitudinally wrapped corrugated steel tape armor, flame-retardant polyethylene sheath outdoor optical fiber cable for communication) The structure of the optical cable is a single-mode or multi-mode The optical fiber is sheathed in a loose tube filled with waterproof compound made of high modulus plastic. 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 plastic-coated aluminum tape is longitudinally wrapped and then extruded with a polyethylene inner sheath, and the double-sided plastic-coated steel tape is longitudinally wrapped and then extruded with a flame-retardant 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

●Excellent pressure resistance

●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: the loose tube is filled with special waterproof compounds; the cable core is completely filled; the moisture-proof layer of plastic-coated aluminum tape and steel tape
Applicable laying

●Directly buried and other places with flame retardant requirements
