Abstract
An optical connector is disclosed. The optical connector includes an optical fiber, a ferrule that holds the optical fiber, the ferrule having a flat ferrule end surface facing a counterpart optical connector, and a spacer provided on the ferrule end surface so as to define a clearance between the ferrule end surface and the counterpart optical connector. A tip surface of the optical fiber is exposed at the ferrule end surface. Respective normal directions to the tip surface of the optical fiber and the ferrule end surface are inclined with respect to an optical-axis direction of the optical fiber in a section along an optical axis of the optical fiber. The spacer includes an opening configured to allow an optical path extending from the tip surface of the optical fiber to pass therethrough.
