PCT No. PCT/JP87/00027 Sec. 371 Date Aug. 18, 1987 Sec. 102(e) Date Aug. 18, 1987 PCT Filed Jan. 19, 1987 PCT Pub. No. WO87/04886 PCT Pub. Date Aug. 13, 1987.An optical space switch is formed in such a manner that switch elements having two inputs and two outputs are arranged in an nxn matrix form and optical signals from n input highways are switched to n output highways. The switch elements are connected in such a manner that the optical signals are always passed through the same number of switch elements, from the input highways to the output highways.
