摘要： A method of polishing an end surface of an optical fiber comprises tilting the central axis of a ferrule integrated with an optical fiber at a preselected angle .THETA. to the axis of rotation of a flat polishing member. A foremost end of the ferrule is then moved into contact with a flat polishing member to polish the foremost end of the ferrule and an end surface of the optical fiber. The foremost end of the ferrule is moved out of contact with the flat polishing member after the ferrule and the optical fiber have been polished into a flat plane. The central axis of the ferrule is then tilted at the angle .THETA. to the axis of rotation of a platen and at an angle .theta.=.THETA.+.DELTA. to a line normal to the surface of the platen, where .DELTA. is an angle of tilt of the rotational platen relative to a flat support surface supporting the rotational platen. Thereafter, the foremost end of the ferrule is moved into contact with a second polishing machine to polish the ferrule and the optical fiber. The ferrule is moved out of contact with the polishing member after the ferrule and the optical fiber have been polished into an oblique convex spherical surface so that an oblique angle defined between a plane normal to the central axis of the ferrule and a tangent plane at the intersection of the central axis of the ferrule and the surface is equal to angle .THETA..

摘要： An end-face lapping apparatus, comprises a rod member W supported on an apparatus main body by a support mechanism through a fixing jig board. A lapping board has a lapping member for lapping the rod member and is rotatably swingably supported on the apparatus main body by a drive mechanism. The drive mechanism causes the lapping board to rotate about a first rotating center and at the same time swivel rotating center about a second rotating center to thereby carry out lapping while urging the rod member W fitted in the fixing jig board against the lapping member of the rotatably swinging lapping board by the support mechanism. The end-face lapping apparatus has a relative position shift device for shifting the relative position of the lapping board and the fixing jig board. The rod member W is lapped at a different portion of the lapping member each time the relative position shift device shifts the relative position of the lapping board.

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.
