摘要： PURPOSE:To easily re-splice optical fiber units by forming a first group as SZ-shaped and a second group in the area moving from a SZ-shaped section to a linear section, and sequentially splicing from optical units of the first group not adjacent to the linear section. CONSTITUTION:At both sides of splicing, a first group 121a and 121b and a second group 122a and 122b of optical fiber units 3a and 3b to be spliced, are faced to each other. And a blank section (F) is maintained between an optical fiber unit close to the linear one and a SZ-shaped optical fiber unit adjacent to it. In order to splice the optical fiber units 3a and 3b, optical fiber units (G) of the first group 121a and 121b located on the boundary between the first group 121a and 121b and the second group 122a and 122b, and not adjacent to linear optical fiber units, are made first and, then, the other units are made sequentially as directed by arrow.

摘要： PURPOSE:To prevent the buckling of an optical fiber unit by arranging the optical fiber unit housed in a metal pipe, the outer periphery of which is covered with a higher-melting-point plastic coating layer, inside or outside of a plastic sheath and applying an iron-wire sheath outside thereof. CONSTITUTION:A cable is made up with a power cable core 1, a metal sheath 2 such as lead sheath for a power cable, an optical fiber unit 3 which is wound on the outer periphery of the metal sheath 2 together with a plastic spacer 4 such as a nylon string spacer, a plastic sheath 6 of polyethylene, etc., an iron-wire sheath 7, etc. The optical fiber unit 3 is one that optical fiber 32 is housed in a metal pipe 31 such as a stainless pipe, the outer periphery of which is covered with a coating layer of higher melting point material than the polyethylene sheath 6. It is thus possible to prevent the optical fiber unit from buckling which occurs in bending operation of the cable.

摘要： PURPOSE:To manufacture a long-sized body of optical fiber compound layer on water bed regardless of the connection of optical fibers as well as main bodies for a long- sized body by winding an optical fiber unit on a plastics sheath formed on the periphery of the long-sized main body, and then laying an iron wire armor outside the wound unit. CONSTITUTION:An optical fiber unit 3 is wound on the periphery of a plastics sheath 2 formed on the periphery of a long-sized main body 1 in a spiral shape, or in a SZ- shaped twisting manner or the like. An optical fiber compound water bed long-sized body is constructed by laying a pressure-wound tape 5 and a seating bed 6 made of polypropylene yarn respectively on a layer consisting of the optical fiber unit 3 wound, and further laying an iron wire armor 7 consisting of many iron wires and an anticorrosive layer 8 made of polypropylene yarn respectively on the bed. The optical fiber unit 3 is compounded with the long-sized main body 1 by employing an iron wire armoring machine to do the work of winding the optical fiber unit 3 round and the work of laying the iron wire armor 7 in tandem with each other. Whatever long size the compound water bed long-sized body has, it may thus be readily manufactured without having any difficulty in connecting an optical fiber.

摘要： PURPOSE:To make it unnecessary to change the specification for each optical fiber to be used by coupling an optical fiber and a photosensitive or a light emitting element through a guide beam fiber in the same diameter as the narrowest fiber among those connected with an optical coupler. CONSTITUTION:A guide beam fiber 5 consisting of a core 5a and clad 5b is provided between a housing 2a and an optical connector coupler 2b and positioning should be made with a spacer so that the core 5a and an optical fiber 4 are aligned on the same axis. Moreover, as a fiber 5, the narrowest fiber among the optical fibers connected to an optical coupler 20 is used. Therefore, when the fiber 4 is coupled with an optical element 2 by the optical coupler 20, the optical element 1 is coupled with the end face of the fiber 5 without relation to the core diameter 4a and the coupling coefficient can substantially be kept constant without relation to the core diameter of connected fiber 4.

摘要： PURPOSE:To detect a supply bobbin residual quantity accurately without causing a malfunction by using a bobbin having a barrel surface whole reflectance is lower than that on the surface of a metallic wire. CONSTITUTION:A material formed by carrying out pear-skin delustering painting on a barrel surface is used as a supply bobbin 1. An address sensor 7 is fixed outside of a stranding machine, and a light emitting body and a light receiving body are arranged on a recumbent U-shaped both side wall, and a shielding plate of a rotary cage 5 passes between them. On the other hand, a reflection type detector is fixed in a position having a constant angle to the sensor 7. When the cage 5 rotates and the plate 6 enters the wall of the sensor 7, an optical path from the light emitting body 10 to the light receiving body 11 is intercepted. A switch of the detector 8 is turned on by means of the signal. When a wire quantity being wound round the bobbin 1 is abundant, the detector 8 detects reflected light caused by a metallic wire, and rotation of the cage 5 is continued, and a wire is stranded. However, when a metallic wire residual quantity of the bobbin 1 is decreased and radiation light to the bobbin comes to be radiated to a barrel surface of the bobbin, a reflected light quantity is decreased and can not be detected, so that the rotation of the cage 5 is stopped.

摘要： PURPOSE:To simplify the manufacture process and reduce the manufacture cost and to relax demands for axis shift characteristics of the optical connector by using a plastic ferrule which is molded integrally with an optical fiber by an insert molding system. CONSTITUTION:A couple of ferrules 2a and 2b are molded integrally with the optical fiber by the insert molding system which uses engineering plastic. Thus, they are constituted in one body to omit a process for mounting the ferrules on the optical fiber. The ferrules 2a and 2b are supported in parallel while penetrating one side wall of a connector case 3, and then coupled with a transmitter receiver. Further, sufficient characteristics can be maintained even when a plastic optical fiber is used, so the plastic optical fiber which is relatively large in diameter is used to offer an inexpensive connector and also relax the demands for the axis shift characteristics of the optical connector.
