Abstract

An optical fiber cable for air-blown installation includes optical fibers acting as a medium for transmitting optical signals; a tube binding the optical fibers; string fillers surrounding the outer periphery of the tube at a predetermined spacing, tensile members positioned between the string fillers to surround the outer periphery of the tube for improving the tensile force of the optical fiber cable; and an outer sheath formed in a flexuous shape to surround the outer circumferences of the string fillers and the tensile members.

Description

technical field [0001] The present invention relates to optical cables, and in particular to optical cables for air blown laying between telephone exchanges and subscriber networks. Background technique [0002] Optical cables are used as a medium for transmitting optical signals through optical fibers. It includes an optical fiber, a tension element, a waterproof element, and an outer jacket to protect and enhance the physical properties of the stranded optical fiber. Optical fibers are glass wires made from materials such as silica, which is mainly derived from quartz, and are easy to handle and lay due to their hair-thin diameter. An optical fiber includes a core for transmitting light therein, a cladding for confining the propagation of light within the core, and a jacket for surrounding the cladding. [0003] Fiber optics have many advantages over coaxial cables, but the problem is that fiber optics are susceptible to physical and environmental factors. Therefore, op...
