摘要： An optical functioning component has a tubular housing with a front end side having substantially the same shape as that of a front end of a removable plug housing of an optical connector plug. A rear end side of the tubular housing has a shape configured for connection to the optical connector plug when the plug housing is removed from the optical connector plug. A ferrule is provided on the front end side of the tubular housing and has a mechanism capable of attenuating, cutting-off, reflecting or absorbing a specific wavelength of light. An optical connection sleeve is connected to an end of the ferrule. A frame supports the ferrule and the optical connection sleeve and is mounted in the tubular housing for undergoing axial movement therein by a preselected amount.

摘要： An optical connector has a ferrule comprises of a cylindrical body for supporting an optical fiber, and a flange member having an end portion connected to a first end of the cylindrical body and a flange part projecting from the end portion. A holding member supports the ferrule and has an engaging part. A rotation positioning part is formed in the flange part of the flange member for positioning the flange part relative to the holding member to provide a first clearance between the rotation positioning part and the engaging part of the holding member for restricting rotation of the ferrule about the fiber optical axis relative to the holding member. A rotation allowing part is formed in the flange part of the flange member and spaced from the engaging part of the holding member to provide a second clearance therebetween greater than the first clearance for allowing rotational movement of the ferrule so as to permit the ferrule to incline in a direction transverse to an axis of the optical connector.

摘要： When plug is fitted to adapter, optical fiber is inserted to an alignment hole for the optical fiber. By providing a taper at the entrance thereof, even if the tip of the optical fiber is deviated from the central position, the deviation is absorbed to make it possible for the optical fiber to be inserted smoothly. When two plugs is fitted to adapter, the tip of one optical fiber is confronted with the other one in the alignment hole, and excessive length L.sub.1 -L.sub.2 is pushed into the two optical fiber-bending spaces with a suitable distribution, thus the optical fiber buckles therein. The end face of the optical fiber is subjected to flat surface-polishing, removal of ripples after being cleaved, or chamfer grinding after being cleaved. The buckling portion of the optical fiber is coated with carbon or the like.
摘要翻译：当插头安装到适配器上时，光纤插入到光纤的对准孔中。通过在其入口处设置锥形，即使光纤的尖端偏离中心位置，也会吸收偏差，使光纤平滑地插入。当适配器安装两个插头时，一个光纤的尖端与对准孔中的另一个光纤面对，并且将长度过长的L1-L2以适当的分布推入两个光纤弯曲空间，因此光纤扣在里面。对光纤的端面进行平面表面抛光，切割后除去波纹，或者在切割后进行倒角研磨。光纤的弯曲部分涂覆有碳等。

摘要： Means and method for assembling an optical fiber cable with a tubular member that secures an outside protective jacket of the cable. The inside wall of the tubular member is provided with serrations such that when the wall is physically reduced on the protective jacket, the serrations engage and retain the jacket without compressing the inner optical fiber so that it is free to move longitudinally within the jacket. This is accomplished by using a crimping device having a crimping aperture that is sized to precisely control the amount of reduction of the tube wall onto the protective jacket.
