Abstract
A ferrule includes a ferrule body and at least one fiber. The fiber is inserted into a through hole axially disposed in the ferrule body, a first end of the fiber is located inside the through hole, an end face of the first end of the fiber is below a plane on which a connection end face of the ferrule body is located, and a first preset distance is a vertical distance between the end face and the plane. The first preset distance causes two abutted ferrules to have a gap between the fibers.
Claims21
A ferrule, comprising:
- a ferrule body aligned along an axial direction of the ferrule, wherein the ferrule body comprises:
- a connection end face;
- and
- a through hole comprising a first section that terminates into a concave orifice having a chamfer, wherein the first section is axially disposed inside the ferrule body, and wherein the chamfer and the connection end face are located on a first plane;
- and
- a fiber configured to be inserted into the through hole, wherein the fiber comprises a first fiber end, wherein the first fiber end comprises a first end face that is disposed at a first distance inside the concave orifice, wherein all outer walls of the first fiber end that are disposed at the first distance include an anti-reflection coating, wherein all internal walls of the concave orifice include the anti-reflection coating, wherein each cross section area of the ferrule body in the first section and in a vertical direction to the axial direction is greater than an area of the first end face, and wherein a projection of the fiber in the axial direction does not coincide with a projection of the each cross section,
- wherein a vertical distance between the first end face and the first plane is a first preset distance,
- wherein the connection end face is configured to abut another ferrule, and
- wherein the first preset distance is configured to leave a gap between the first end face and a second fiber of the other ferrule when the ferrule abuts the other ferrule.

A fiber connector, comprising:
- a housing;
- and
- a ferrule configured to be fastened to the housing, wherein the ferrule comprises a ferrule body and at least one fiber, wherein the ferrule body is aligned along an axial direction of the ferrule body and comprises:
- a connection end face;
- a through hole comprising a first section that terminates into a concave orifice having a chamfer, wherein the through hole is axially disposed inside the ferrule body, wherein the chamfer and the connection end face are located on a first plane;
- and
- a fiber configured to be inserted into the through hole, wherein the fiber comprises a first fiber end, wherein the first fiber end comprises a first end face that is disposed at a first distance inside the concave orifice, wherein all outer walls of the first fiber end that are disposed at the first distance include an anti-reflection coating, wherein all internal walls of the concave orifice include the anti-reflection coating, wherein each cross section area of the ferrule body in the first section and in a vertical direction to the axial direction is greater than an area of the first end face, and wherein a projection of the fiber in the axial direction does not coincide with a projection of the each cross section, wherein a vertical distance between the first end face and the first plane is a first preset distance, wherein the connection end face is configured to selectively abut another ferrule, and wherein the first preset distance is configured to leave a gap between the first end face and a second fiber of the other ferrule when the ferrule abuts the other ferrule.
