1. An optical connector comprising:
multiple optical fibers;
a single multicore fiber; and
multiple self-forming optical waveguides,
wherein the total number of cores of the multiple optical fibers and the total number of cores of the multicore fiber are identical to each other,
the multiple optical fibers and the multicore fiber are arranged facing each other,
the self-forming optical waveguides are provided among the multiple optical fibers and the multicore fiber,
end portions of the self-forming optical waveguides are optically connected to the cores of the multiple optical fibers and the cores of the multicore fiber,
either the multiple optical fibers or the multicore fiber contacting the end portions of the self-forming optical waveguides is detachable from the self-forming optical waveguides,
the cores of the multicore fiber are arrayed in a non-linear shape, and
the cores of the multicore fiber are positioned such that the cores of the multicore fiber partially overlap with each other in a first direction perpendicular to a second direction which is a direction parallel with a longitudinal direction of the multicore fiber and not overlap with each other in the second direction and a third direction perpendicular to the first direction and the second direction.
