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.
摘要翻译：在光连接器中，保持多根光纤的一对套圈的端面被定位成具有两个引导销并彼此对接以连接该对套圈中的光纤。光连接器设置有用于将端面彼此推动的推动构件。端面以一定角度研磨。引导销和引导孔之间的间隙，其在端面处开放并且引导销装配到该引导孔中的间隙大于0.004mm且小于或等于0.008mm。当导销插入并插入引导孔时产生的摩擦引起的粉末大大减少。即使进行频繁的连接和断开连接，连接损失也不会增加，并且不需要清洁连接器。

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.
