PROBLEM TO BE SOLVED: To provide an optical fiber switching circuit in which optical fiber switches capable of changing over and connecting a large number of circuits by a few actuater are combined. SOLUTION: This optical fiber switching circuit is constituted by combining at least a group of N×2N (N=2) optical fiber switches 62 using optical fiber element wires used for changing over and connecting N pieces of movable side optical fibers from N pieces of 2N fixed side optical fibers to the other N pieces with other optical switches 61, 63. Namely, 1×2N (N>=2) optical switch circuits, N×N matrix optical fiber switching circuits, and 2×4N (N>=2) optical fiber switching circuits are constituted. |
