1. An optical connector having a central axis extending between a front end and a rear end, comprising:
a rear housing located at the rear end of the optical connector, the rear housing allowing an optical fiber cable to be inserted therethrough;
an inner housing comprising at least one retaining hole configured to accommodate a ferrule at a distal end thereof, a rear portion of the inner housing being accommodated in the rear housing; and
an outer housing disposed on an outer periphery of the inner housing to cover a front portion of the inner housing, the outer housing being configured to rotate with respect to the inner housing about the central axis by a rotation guiding mechanism cooperating with an adapter for connecting the optical connector to another optical connector,
wherein the outer housing includes a front wall covering the distal end of the inner housing, the front wall includes at least one opening region, and the opening region is configured to correspond to a fiber exposed surface of the ferrule when the outer housing is rotated with respect to the inner housing from an initial position to a connected position by the rotation guiding mechanism.
