The pore part 8 has an inner diameter sized to allow bending of the optical fiber. The optical fiber bending regulating part 9 is a cylinder which is located at a portion nearer to the ferrule 1 than a center position of the pore part 8 and has a major axis on a center axis of a major axis direction of the ferrule 1, and has a hole diameter slightly larger than an outer diameter of the coated portion of the optical fiber. The optical fiber holding part 3 elastically holds the coated portion of the optical fiber in the state of an end of the optical fiber projecting from an end face of the ferrule 1 and presses and connects end faces of optical fibers with each other by elastic recovery force generated by bending of the optical fibers.

摘要： PROBLEM TO BE SOLVED: To restrain damage of the front end face of an optical fiber in a chamfering process without complicating the structure of a holder. SOLUTION: A polishing surface 24 of a polishing member 10 intersects with the axis of an intermediate part of an optical fiber F, and also inclines to the orthogonal plane of the axis of the intermediate part of the optical fiber F. When optical fiber F is made to approach the polishing surface 24, the tip of the optical fiber F obliquely comes into contact with the polishing surface 24, and also in separating, the tip of the optical fiber F separates from the polishing surface 24 while keeping its oblique attitude to the polishing surface, so that damage of the front end face of the optical fiber F can be restrained. Since the track of the polishing member 10 includes a revolution component and a rotation component, a large polishing amount can be obtained and also abrasion of the polishing member 10 can be restrained, although the position of the tip of the optical fiber F is in the vicinity of a revolution axis (ar).

摘要翻译：要解决的问题：在倒角过程中抑制光纤前端面的损伤而不会使保持器的结构复杂化。解决方案：抛光构件10的抛光表面24与光纤F的中间部分的轴线相交，并且也倾斜到光纤F的中间部分的轴线的正交平面。当光学使纤维F接近研磨面24，光纤F的前端倾斜地与研磨面24接触，并且在分离时，光纤F的前端与研磨面24分离，同时保持其倾斜对抛光面的姿态，能够抑制光纤F的前端面的损伤。由于抛光构件10的轨道包括旋转分量和旋转分量，所以可以获得大的抛光量，并且即使光纤F的尖端的位置在...中，也可以抑制抛光构件10的磨损旋转轴（ar）附近。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an optical fiber coupling member to which an optical fiber is fixed in order to connect the optical fiber to a waveguide-type optical element and which is capable of reducing curvature when the optical fiber is buckled.SOLUTION: An optical fiber coupling member 200 has a cavity 201 for securing an optical fiber 10 and a recessed portion 202 around the cavity 201 on a surface 200B opposite a coupling surface 200A to be coupled with a waveguide-type optical element 30. By providing the recessed portion 202 around the cavity 201 on the surface 200B opposite the coupling surface 200A, a buckling structure 10A of the optical fiber 10 can start inside the optical fiber coupling member 200. Thus, a longer region is secured for the buckling structure 10A of the optical fiber 10 without making the optical fiber coupling member 200 shorter, which allows for reducing curvature of the optical fiber 10.

摘要： PROBLEM TO BE SOLVED: To provide a novel means capable of suppressing damage to a front end surface of a single core optical fiber. SOLUTION: A polishing member 25 includes a polishing part 25a exerting a polishing action, and a protection part 25b not exerting a polishing action. An optical fiber F is elastically transformed by a driving mechanism with the tip of the optical fiber F abutting on the protection part 25b of the polishing member. Thereafter the tip of the optical fiber F is allowed to abut on the polishing part 25a with the axis of the tip of the optical fiber F not perpendicular to the surface of the polishing part 25a. Therefore, the abutting between the front end surface of the optical fiber F and the polishing part 25a is suppressed, and the damage to the front end surface is suppressed.

摘要： PROBLEM TO BE SOLVED: To provide an optical fiber connector whose reliability can be improved.
SOLUTION: In the optical fiber connector, an end face 802 of an optical fiber fixed to a plug in a cantilever shape is connected in a thin hole 914 whose diameter is slightly larger than an outer diameter of the optical fiber 802. A relation of a chamfering angle θ' of the optical fiber 802, a chamfering angle ψ of an entrance of the thin hole 814, a length L of the optical fiber 814 in a cantilever state and an angle α=tan
-1 (δπ/L) derived from an amplitude amount δof a bend of the optical fiber 802, which occurs when the chamfering part of the optical fiber 802 is brought into contact with a thin hole entrance chamfering part 818, is θ'>ψ+α. Since the end face of the optical fiber 802 is chamfered, the optical fiber 802 can be inserted into the thin hole 814 without making dust 302 adhere to the end face of the optical fiber 802.
