Abstract
An optical ferrule butt-connected in an optical adapter, includes: a ferrule main body; a connection end face in a front surface of the main body; a pair of grooves on the connection end face of the main body; guide pin insertion holes in bottom surfaces of the respective grooves; optical fiber insertion holes in the connection end face, the holes being arranged in a line; and foreign material collecting portions at least at a pair of corresponding sides of the connection end face. The groove has a width larger than a diameter of the guide pin insertion hole. The foreign material collecting portions respectively have a wall for connecting the connection end face with a side surface of the ferrule main body to form a space for collecting a foreign material with an opposite connection end face of a corresponding optical ferrule and an inner wall of the optical adapter.
