摘要： Universal optical fiber connectors and their basic plugs, wherein the optical fiber connectors have some common elements for their connector-functions to permit an installation of optical fiber into one of the different type connectors for establishing their connection more easily and to facilitate a tuning operation with positioning key maintaining the same direction between eccentricity of the fiber core and the key. The basic plug has a ferrule, a spring element, and a cylindrical tube. The spring element is positioned between a ferrule and a cylindrical tube, so that it exerts forces toward them in an axial direction. The ferrule has a common dimensional structure for securing an optical fiber and has a shape enabling the connection to any one of various kinds of housing members. Thus, the basic plug connects separate optical fibers together through the housing member.

摘要： An optical fiber connector for connecting an optical fiber cable to a ferrule comprises a tubular body having a first end portion for connection to a peripheral surface of a ferrule, a second end portion for connection to a peripheral surface of an optical fiber cable, a step portion interconnecting the first end portion to the second end portion, and a clamping portion for clamping the optical fiber cable to the ferrule. The clamping portion extends inwardly from a terminal end of the second end portion towards the central axis of the tubular body but does not project lengthwise from the terminal end of the second end portion in the direction of the central axis. The first end portion, the second end portion, the step portion and the clamping portion of the tubular body have approximately the same wall thickness.
