    摘要： A wire laying apparatus comprising a first carrier member, a second carrier member having one end connected to the first carrier member, a communication wire disposed within the second carrier member, and a compressor connected to and supplying a fluid under pressure to a second end of the second carrier member through which the fluid supplied by the compressor serves to move the communication wire from the second carrier member to the first carrier member. The wire laying apparatus may be restructured to serve as a wire collecting apparatus.

    摘要： An optical fiber unit including a plurality of sub-units. Each sub-units includes a plurality of optical fibers. Further, the sub-units are twisted together, with a twist pitch in the range of from 30 to 600 mm. Each group of optical fibers are coated with a primary layer to form a sub-unit. The sub-units are then twisted together and coated by a secondary coating. A porous layer is applied onto the secondary layer, thus forming the optical fiber unit.

    摘要： The invention relates to an apparatus for laying an optical fiber unit with a pressure fluid into a previously laid duct line. Specifically, the apparatus performs this operation by a method for causing pressure fluid to flow backward into the guide tube on the feed side of the optical fiber unit so as to generate a buoyant force, so that the load due to the frictional force in the section between the feed side and the driving means can be much reduced. Accordingly, the method according to the present invention is particularly useful for pressure-sending an optical fiber unit into a duct line having insertion resistance, for example, a vertical duct line, a duct line having fine curves, or the like.

    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.

    摘要： A method of measuring a length of a conduit comprises the steps of: supplying air into a conduit to insert a filamentary body into the conduit by flow of the air; detecting arrival of a forward end of the filamentary body at an outlet of the conduit; and measuring the length of the conduit from the length of the filamentary body inserted into the conduit. An apparatus for measuring a length of a conduit, comprises an air supply device for supplying air into the conduit; a filamentary body including a wire and a plurality of elastic large-diameter members attached to the wire; and a device for detecting that a forward end of the filamentary body arrives at an outlet end of the conduit, where the length of the conduit is measured from the length of the filamentary body inserted into the conduit.
