摘要： PROBLEM TO BE SOLVED: To provide an optical connector that preferably transmits light by desirably eliminating such trouble that loss of transmitted light is generated by reducing flexure of an insert optical fiber flexed to make tips of an internal optical fiber and the insert optical fiber securely abut against each other. SOLUTION: The optical connector includes a cover body 40 pivoted to rotate between a standby position where an anchor member 60 is enabled to approach a connector main body 10 and a holding position where the anchor member 60 is set and held. On an internal surface of the cover body 40, an abutting projection part 43 which abuts against a tip-side wall surface of the anchor member 60 is provided to project, and when the cover body 40 rotates from the standby position to the holding position, the abutting projection part 43 abuts against the tip-side wall surface of the anchor member 60 to push and move the anchor member 60 backward.

摘要： PROBLEM TO BE SOLVED: To provide a ferrule-attached polarization maintaining optical fiber that is easily manufactured and its manufacturing method.
SOLUTION: A polarization maintaining optical fiber 1 is inserted into an optical fiber hole 12a of a square ferrule 12 for a single coated fiber, in a manner that the direction of the polarization axis corresponds to the side of a square cross section of the square ferrule 12, and is then fixed with an adhesive 13 to constitute the ferrule-attached polarization maintaining optical fiber 11. The manufacturing method is such that the polarization maintaining optical fiber 1 is held by a fiber holder, with the direction of the polarization axis oriented as prescribed, that the fiber holder and a ferrule holder are housed together in a guiding groove of a guiding member, wherein the ferrule holder holds the square ferrule 12 with the adhesive filled in the optical fiber hole 12a, and that the fiber holder and the ferrule holder are made to approach to each other, with the polarization maintaining optical fiber 1 inserted into the optical fiber hole 12a. Since the direction of the polarization axis can be adjusted without rotating the polarization maintaining optical fiber 1, the polarization maintaining optical fiber 1 is hardly damaged by a sharp edge 12c at the entrance of the optical fiber hole 12a.

摘要： PROBLEM TO BE SOLVED: To provide an optical fiber for an optical connector, an optical fiber that can suppress connection loss, cracking, chipping, etc., of an optical fiber, and also to provide an optical connector using the same. SOLUTION: The optical fiber 20 for an optical connector is designed to be fixedly inserted into the optical fiber inserting hole 21 that is formed in a ferrule 22 of an optical connector 10, wherein an end face 20b on the side projecting from the rear end 22b opposing to the tip end face 22a of the ferrule 22 is machined in a rounded lens shape. Machining the end face 20b this way eliminates interference between fiber edges even if a bend is caused at the tip end of an opposite optical fiber to be connected, making butt connection possible in a manner reducing a gap between the cores of the opposite optical fiber and the inserted optical fiber. In addition, the machining the end face in the shape of a lens increases the numerical aperture, suppressing connection loss due to angular deviation. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：为了提供一种用于光连接器的光纤，可以抑制光纤的连接损耗，破裂，碎裂等的光纤，并且还提供使用该光纤的光连接器。解决方案：用于光学连接器的光纤20被设计成固定地插入到形成在光连接器10的套圈22中的光纤插入孔21中，其中从侧面突出的一侧的端面20b 与套圈22的前端面22a相对的后端22b被加工成圆形透镜形状。这样加工端面20b即使在要连接的相对的光纤的尖端处产生弯曲也可以消除光纤边缘之间的干扰，从而可以以减小相对光纤的芯之间的间隙和插入的光纤。此外，以透镜形状加工端面增加数值孔径，从而抑制由于角度偏差引起的连接损失。版权所有（C）2006，JPO＆NCIPI
