Product description
GYFTY (non-metallic strengthening member, loose tube stranded and filled, polyethylene sheathed outdoor optical fiber cable for communication) The structure of the optical cable is to sheath a single-mode or multi-mode optical fiber into a high-modulus plastic filled with waterproof compound loose In the casing. The center of the cable core is a non-metallic reinforced core (FRP). For certain fiber optic cables, a layer of polyethylene (PE) is extruded outside the non-metallic reinforced core or a non-metallic reinforced yarn is added to the cable core. line. The loose tube (and 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 polyethylene sheaths.
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 excellent flexibility and bending resistance
●Optical cables are all non-metallic structures, light in weight, easy to lay, and excellent in electromagnetic resistance
●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 compound; the cable core is completely filled
Applicable laying
Power system, heavy lightning and places with severe electromagnetic interference
