PURPOSE:To provide an optical switch whose structure is simplified, whose size is small, whose assembling adjustment is simplified, and whose switching speed is increased, as to a fiber direct-movement system 1X4 changeover optical switch. CONSTITUTION:This switch is the fiber direct-movement system changeover optical switch, and a movable fiber 18 constituted of one fiber is arranged on one side and a movable fiber array 26 constituted of four fibers is arranged on the other side with an array 21 constituted of two fibers interposed between the them so that respective optical axes may be aligned, and also a driving means for respectively driving the movable fiber 18 and the movable fiber array 26 is installed. |
