The structure of the photoelectric hybrid cable for the access network is to insert a 250 μm optical fiber into a loose tube made of a high modulus material, and the loose tube is filled with a waterproof compound. The center of the cable core is FRP or metal reinforcement (metal reinforcement plus a layer of PE cushion). The wire and the loose tube (and the filling rope) are twisted around the central reinforcing core into a compact and round core, and the gap in the core is filled with a water blocking filler. The double-coated steel strip is longitudinally extruded and extruded into a polyethylene or low-smoke halogen-free (LSZH) jacket.
Features and applications
●Good flexibility and mechanical properties;
● Photoelectric integration, fully saving pipeline resources;
● Pipe installation and overhead installation.
