ABSTRACT:
In constructing an optical wiring network for connecting optical information processors on a plurality of floors of a building by pressure-feeding an optical fiber cable through a tube using a compressed gas provided by a pressure feeding apparatus, a cable installation route and a pressure of the compressed gas at the entrance end of the tube are first determined so that thrust exerted on the optical fiber cable by the compressed gas is greater, at every point of the route, than resistance including weight of the optical fiber cable in an ascending portion of the route and friction between the optical fiber cable and the tube. After installation of a tube in the building along the determined route, an optical fiber cable is fed through the installed tube with the pressure feeding apparatus, employing the above-determined pressure of the compressed gas at the entrance end.
