Product description
GYTY53 (metal strengthening member, loose tube layer stranded filling type, polyethylene sheath, longitudinally wrapped corrugated steel tape armor, polyethylene sheathed outdoor optical fiber cable for communication) The structure of the optical cable is a single-mode or multi-mode optical fiber sheathed by a high-mode optical fiber The waterproof compound loose tube is filled with a large amount of 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 cable core is extruded with a layer of polyethylene inner sheath, and the double-sided plastic coated steel tape is longitudinally wrapped and then the plastic polyethylene sheath is extruded.
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
●Excellent pressure resistance
●Smooth outer sheath enables the optical cable to have a smaller coefficient of friction during installation
●The following measures are adopted 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 plastic-coated steel belt is moisture-proof
Applicable laying
● Buried/underground
