Optical connector and optical connection structure

Abstract

This optical connector comprises: a ferrule having a plurality of fiber holes and an introduction hole; and a plurality of optical fibers inserted through the introduction hole into the fiber holes. The introduction hole has a rear end opening on a rear end face opposite to the connection end face of the ferrule. The optical fibers include a plurality of optical fiber groups having a plurality of optical fibers. The optical fiber groups are introduced from the rear end opening into the introduction hole and respectively inserted into the fiber holes. The fiber holes are formed at different positions in a first direction on the connection end face. Two or more of the optical fibers included in each optical fiber group have different positions in a second direction at the rear end opening.
