UV optical fiber bundle based high-performance micro air-blowing optical cable

The utility model relates to the technical field of optical cables, especially to a UV optical fiber bundle based high-performance micro air-blowing optical cable. The optical cable comprises multiple UV optical fiber bundle units, the UV optical fiber bundle units are mutually twisted in an S manner to form a cable core, the cable core is internally provided with a nonmetal central reinforcing piece, a plastic sleeve layer of the central reinforcing piece is arranged outside the nonmetal central reinforcing piece, a polyethylene sheath is extruded outside the multiple UV optical fiber bundle units, and a water blocking material is arranged among the UV optical fiber bundle units. According to the utility model, the structure of a micro air-blowing optical cable is improved to greatly reduce indexes as the duty ratio of the optical cable and a pipeline, the weight of the optical cable and the diameter of the optical cable and increase the blowing distance, namely the external diameter is only 7.4mm, the weight is as low as 45Kg/Km, the blowing distance is as long as 1200M, and the duty ratio (14mm/10mm) is as low as 55%.
