    摘要： In an optical connector, end faces of a pair of ferrules that hold multiple optical fibers are positioned with two guide pins and butted against each other to connect the optical fibers in the pair of ferrules. The optical connector is provided with an urging member for pushing the end faces against each other. The end faces are ground at an angle. The gap between the guide pins and guide holes, which open at the end faces and into which the guide pins are fitted, is larger than 0.004 mm and smaller than or equal to 0.008 mm. Powder caused by the friction generated when the guide pins are inserted and fitted into the guide holes is greatly reduced. Connection loss does not increase even when frequent connection and disconnection are performed, and cleaning the connector becomes unnecessary.

    摘要： A core detaching tool for an optical fiber cable detaches one or more optical fiber tape units accommodated in a sheath of the optical fiber cable by tearing the sheath. The core detaching tool for an optical fiber cable is provided with a pair of cable holding parts, and a moving mechanism for moving the cable holding parts. A pair of projected parts are formed inside the cable holding parts, and a distance between the projected parts is greater than a long side face of a cross section of the optical fiber tape unit. The optical fiber tape unit can be separated and detached from the sheath in intermediate post-branching of the optical fiber cable without increasing a transmission loss.

    摘要： A hollow fiber has a hollow tube, a reflecting film formed on an inner wall of the hollow tube, and the reflecting film is a first metal film formed by baking a first metal nano particle solution including a first metal nano particle. The hollow fiber may have a transparent film on the first metal film. The transparent film is formed by baking or chemically reacting from a second metal nano particle included in a second metal nano particle solution.
