Abstract: The present invention relates to the provision of a ferrule that can be connected even when the space for the connection is small. A ferrule of the present invention is configured to hold a plurality of optical transmission members and to be connected to another ferrule. The ferrule includes a first surface facing the end of the optical transmission members when the optical transmission members are held; and a plurality of second surfaces disposed opposite to the first surface in the ferrule. In the ferrule, the optical transmission members extend in the Z direction, and the ferrule is configured to be moved in a direction orthogonal to the Z direction to be connected to the other ferrule.

Abstract: A ferrule includes a holding part, a first surface and a second surface. The holding part includes a first holding recess including the first surface and a third surface facing the first surface, a first wall, at least one through hole that is open at the third surface and a fourth surface, the fourth surface being located on a side on which the plurality of optical transmission members is inserted, and a plurality of first grooves disposed at the first holding recess along an extending direction of the plurality of optical transmission members, the plurality of optical transmission members inserted to the at least one through hole is respectively disposed at the plurality of first grooves.

Abstract: A ferrule includes a holding part, a first surface, and a second surface. The holding part includes a holding recess, a first groove disposed at the holding recess along an extending direction of the optical transmission member, the first groove being a groove where the optical transmission member is disposed, a pressing member configured to press the optical transmission member toward the first groove, and a sliding part disposed at the holding recess and the pressing member, and configured to slide the pressing member with respect to the holding recess along the extending direction of the optical transmission member.

Abstract: A ferrule includes an optical transmission member holding part configured to hold an optical transmission member; a first surface that faces an end portion of the optical transmission member when the optical transmission member is held at the optical transmission member holding part; and a through hole that is open between the optical transmission member holding part and the first surface.
