摘要： A diffraction grating portion (12) is formed in an optical fiber (10), having a diameter of 125 .mu.m and serving to transmit light, along its optical axis. The optical fiber is concentrically surrounded by a lower coating portion (14) having an outer diameter of 300 .mu.m and consisting of a silicone resin. The lower coating portion is concentrically surrounded by a coating portion (16) having an outer diameter of 900 .mu.m and consisting of a liquid crystal polymer, e.g., polyester amide. The coating portion is further surrounded by an outermost coating portion (18) having an outer diameter of 1 mm and consisting of a UV curing resin colored for identification. Both the optical fiber (10) and the lower coating portion (14) have positive thermal expansion coefficients. In contrast to this, the coating portion (16) consisting of the liquid crystal polymer has a negative thermal expansion coefficient.

摘要： 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.
