Abstract

PURPOSE:To enable an optical fiber to be switched over to another without bending by switching over a photo signal with a fixed mirror and a plane mirror capable of moving along one optical path of optical fibers arranged in rows on a plane and of selectively stopping at another optical path. CONSTITUTION:Optical fiber rows 4 (41, 42...4n) formed by arranging a plurality of optical fibers in rows on a plane are provided with light converging optical units 5 (51, 52...5n) at ends so that each unit 5 coincides with the optical axis of each row 4. Fixed plane mirror 6 is set at a predetermined angle, and plane mirror 7 is placed at the complementary angle to mirror 6 so that mirror 7 can be moved along optical path D of optical fiber 4n farthest from mirror 6. By moving mirror 6 fiber 4n can be switched over to desired fiber 4 and connected.
