Document Type and Number:
Japanese Patent JP7047314
Kind Code:
B2
Abstract:
An optical connector includes an optical fiber, a ferrule holding the optical fiber, and a plug frame accommodating the ferrule. The optical fiber includes a glass fiber and a resin coating surrounding the glass fiber. The ferrule has a through-hole inside the ferrule and a flange outside the ferrule. The flange has a quadrangular cross-section perpendicular to the through-hole. The ferrule holds the glass fiber in the through-hole. The plug frame has a quadrangular tubular cross-section perpendicular to the through-hole. In one aspect, the flange has first and second faces opposing each other with the through-hole there between and third and fourth faces opposing each other with the through-hole there between and orthogonal to the first and second faces. The plug frame has two alignment parts capable of supporting the first and second faces, and there are clearances between the plug frame and the third and fourth faces.
