Abstract
A ferrule includes: a ferrule body including a first body-side guide hole into which a first guide pin is inserted, a second body-side guide hole into which a second guide pin is inserted, and an optical fiber holder that holds an optical fiber; and a lens plate including a first plate-side guide hole into which the first guide pin is inserted, a second plate-side guide hole into which the second guide pin is inserted, a lens part, and an abutment surface that an end face of the optical fiber abuts. The first guide pin fits the first body-side guide hole and the first plate-side guide hole. The second guide pin fits one of the second body-side guide hole or the second plate-side guide hole.
Claims4
A ferrule comprising:
- a ferrule body comprising:
- a first body-side guide hole into which a first guide pin is inserted;
- a second body-side guide hole into which a second guide pin is inserted;
- and
- an optical fiber holder that holds an optical fiber;
- and
- a lens plate comprising:
- a first plate-side guide hole into which the first guide pin is inserted;
- a second plate-side guide hole into which the second guide pin is inserted;
- a lens part;
- and
- an abutment surface that an end face of the optical fiber abuts, wherein
- the first guide pin fits the first body-side guide hole and the first plate-side guide hole,
- the second guide pin fits one of the second body-side guide hole or the second plate-side guide hole,
- the other one of the second body-side guide hole and the second plate-side guide hole has a diameter greater than a diameter of a hole fitted by the second guide pin,
- the ferrule body comprises a body-side positioner,
- the lens plate comprises a plate-side positioner, and
- when the body-side positioner contacts the plate-side positioner, the lens plate is positioned with respect to the ferrule body in a direction perpendicular to a plane including a central axis of the first plate-side guide hole and a central axis of the second plate-side guide hole.
A fiber-equipped ferrule, comprising:
- an optical fiber;
- a ferrule body comprising:
- a first body-side guide hole into which a first guide pin is inserted;
- a second body-side guide hole into which a second guide pin is inserted;
- and
- an optical fiber holder that holds an optical fiber;
- and
- a lens plate comprising:
- a first plate-side guide hole into which the first guide pin is inserted;
- a second plate-side guide hole into which the second guide pin is inserted;
- a lens part;
- and
- an abutment surface that an end face of the optical fiber abuts, wherein
- the first guide pin fits the first body-side guide hole and the first plate-side guide hole,
- the second guide pin fits one of the second body-side guide hole or the second plate-side guide hole,
- the other one of the second body-side guide hole and the second plate-side guide hole has a diameter greater than a diameter of a hole fitted by the second guide pin,
- the ferrule body comprises a body-side positioner,
- the lens plate comprises a plate-side positioner, and
- when the body-side positioner contacts the plate-side positioner, the lens plate is positioned with respect to the ferrule body in a direction perpendicular to a plane including a central axis of the first plate-side guide hole and a central axis of the second plate-side guide hole.
A method for manufacturing a ferrule that comprises:
- an optical fiber;
- a ferrule body;
- and a lens plate, the method comprising:
- inserting a first guide pin and a second guide pin into a first body-side guide hole of the ferrule body and a second body-side guide hole of the ferrule body, respectively;
- inserting the first guide pin and the second guide pin into a first plate-side guide hole of the lens plate and a second plate-side guide hole of the lens plate, respectively;
- and
- positioning the lens plate with respect to the ferrule body in a direction perpendicular to a plane including a central axis of the first plate-side guide hole and a central axis of the second plate-side guide hole by making a body-side positioner of the ferrule body come into contact with a plate-side positioner of the lens plate.
