<p>The present invention relates to an optical switch. The optical switch comprises: a body having a cylindrical shape and a plurality of optical signal output holes which are through holes formed on the outer periphery thereof; a screw positioned inside the body in the longitudinal direction of the body and having a rotor; a first motor positioned inside the body and generating power to linearly move the screw using power received from the outside; a second motor positioned inside the body and generating power to rotate the screw using power received from the outside; and a control unit positioned inside the body and determining through which one of the optical signal output holes outputs an optical signal received from the outside, thereby switching the optical signal transmitted from the outside to the optical signal output holes through the rotor and thus outputting the optical signal to a plurality of channels without optical loss to improve optical communication efficiency.</p> |
