OPTICAL SWITCH FOR CHANGING OVER CONNECTIONS OF OPTICAL SIGNALS TRANSMITTED OVER PLURAL OPTICAL FIBERS AND OPTICAL SWITCH SYSTEM USING THE SAME

摘要

PURPOSE: An optical switch for changing over connections of optical signals transmitted over plural optical fibers and an optical switch system using the same are provided to reduce a size of the optical switch by arranging effectively components within the optical switch. CONSTITUTION: A collimator array(4) is formed with a plurality of collimators coupled to optical fibers(2). A mirror array(6) includes a plurality of movable mirrors(5). The movable mirrors are optically coupled to light outputted from a first collimator of the collimator array. A first mirror(7) is optically coupled to the light outputted from the mirror of the mirror array. A second mirror(8) is optically coupled to the light outputted from the first mirror. A second collimator of the collimator array is optically coupled to the light outputted from the second mirror. The light outputted from the second mirror passes the first mirror and the mirror array and optically couples to the second collimator.
