    • 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..
    • 抛光光纤端面的方法包括将与光纤集成的套圈的中心轴以预定角度THETA倾斜到平面抛光件的旋转轴线。 然后将套圈的最前端移动成与平坦的抛光构件接触以抛光套圈的最前端和光纤的端表面。 在套圈和光纤被抛光成平面之后,套圈的最前端与平面抛光部件脱离接触。 然后将套圈的中心轴线以角度THETA倾斜到压板的旋转轴线,并以θ= THETA + DELTA的角度倾斜到与压板表面垂直的线,其中DELTA是倾斜角 旋转压板相对于支撑旋转压板的平坦支撑表面。 此后,使套圈的最前端与第二抛光机接触以对套圈和光纤进行抛光。 在套圈和光纤被抛光成倾斜的凸形球面之后,套圈移动离开与抛光构件的接触,使得在垂直于套圈的中心轴线的平面和 套圈的中心轴线与表面的交点等于角度THETA。
