The present disclosure relates to a multi-fiber optical ferrule that includes a protrusion on the ferrule end face that surrounds and encompasses ferrule microholes on the ferrule end face. The protrusion is shaped and is deformable upon contact with a contact target such that alignment of optical fibers within the ferrule can be controlled. Stated another way, the protrusion enables precision control of the fiber position relative to the ferrule end face.

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.

An optical connection component includes: a glass plate formed of a glass material capable of transmitting ultraviolet rays, the glass plate having a first surface, a second surface opposite to the first surface, and one or a plurality of first through holes penetrating from the first surface to the second surface; a resin ferrule fixed to the first surface of the glass plate and having one or a plurality of second through holes each having a central axis coaxial with the central axis of the one or a plurality of first through holes; and one or a plurality of optical fibers including a glass fiber and a resin coating covering the outer periphery of the glass fiber, wherein the glass fiber exposed from the resin coating at the tip end of each of the one or a plurality of optical fibers is received in the one or a plurality of first through holes and the one or a plurality of second through holes.

A ferrule includes: a tip surface; an opening portion provided on a side opposite to the tip surface in a first direction intersecting the tip surface; a plurality of fiber grooves extending along the first direction and arranged along a second direction intersecting the first direction between the tip surface and the opening portion, the plurality of fiber grooves being capable of respectively supporting a plurality of optical fibers; and a plurality of lenses respectively disposed on extension lines of the plurality of fiber grooves. The fiber groove has a first fiber groove portion for positioning the optical fiber with respect to the lens and a second fiber groove portion for introducing the optical fiber into the first fiber groove portion. The first fiber groove portion is disposed closer to the lens than the second fiber groove portion in the first direction.

A ferrule for retaining a plurality of optical fibers includes a front end surface; a rear end surface; a plurality of fiber retaining holes; an accommodation hole; and a void portion. The fiber retaining holes each extend from the front end surface toward the rear end surface along a first direction. The accommodation hole is connected to the plurality of fiber retaining holes. The void portion is provided in a region around the plurality of fiber retaining holes. The fiber retaining holes include constant diameter portions extending from the front end surface along the first direction. The void portion is provided along the constant diameter portions, and is aligned with the constant diameter portions in a plane perpendicular to the first direction. A minimum value of a width in the plane of the void portion differs from an inner diameter of the constant diameter portion.

An optical ferrule includes at least one light affecting element configured to affect one or more characteristics of light from an optical waveguide as the light propagates in the optical ferrule, the light affecting element having an input surface. At least one receiving element receives and secures the optical waveguide to the ferrule so that an output surface of the waveguide is optically coupled to the input surface of the light affecting element. A waveguide stop limits movement of the waveguide toward the input surface of the light affecting element when the optical waveguide is installed in the receiving element. A space between the output surface of the optical waveguide and the input surface of the light affecting element is inaccessible to the optical waveguide when the optical waveguide is installed in the receiving element.
