Abstract
A rotary switch type optical fiber switch according to the present invention includes a plurality of lined-up sleeves disposed on at least one concentric circle about a reference axis and a fixed side ferrule with optical fiber mounting plate assembly for supporting fixed side ferrules with optical fibers. A movable side ferrule with optical fiber assembly supports a movable side ferrule with an optical fiber in parallel with the reference axis at a position apart from the reference axis a distance corresponding to the radius of the concentric circle and rotates about the reference axis as well as is movable in parallel with the reference axis. A movable side ferrule with optical fiber mounting plate driving unit assembly locates the movable side ferrule at the angular position of an arbitrary lined-up sleeve of the fixed side ferrule mounting plate at a position apart from the fixed side ferrule mounting plate to thereby insert the movable side ferrule into the lined-up sleeve and connect it to one of the fixed side ferrules with the optical fibers.
