Product description
GYTS (metal strengthening member, loose tube stranded and filled, steel-polyethylene bonded sheathed outdoor optical fiber cable for communication) The structure of the optical cable is to sheath single-mode or multi-mode optical fiber into 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 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 steel-plastic composite tape is longitudinally wrapped and then extruded 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
●Steel-polyethylene sheath has excellent compressive performance
●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 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 with a steel-plastic composite with a moisture-proof layer.
Applicable laying
● Buried/underground
