Ferrule, fiber-equipped ferrule, and method for manufacturing fiber-equipped ferrule
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.
1. 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.
2. The ferrule according to claim 1 , wherein
the second guide pin fits the second body-side guide hole, and
the second plate-side guide hole has a diameter greater than a diameter of the second body-side guide hole.
3. 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.
