Abstract

PURPOSE:To uniform connection loss between optical fibers and switching time by coupling a 1st optical fiber with a 2nd optical fiber and arranging a shutter on an optical path between both the optical fibers. CONSTITUTION:For instance, light beams propagated through an optical fiber 1a passes a shutter 8a when the shutter 8a is opened, arrives at a reflector 6a and is refracted twice by the reflectors 6, 7 and then guided to an optical fiber 3. Light beams propagated through optical fibers 1b-1h are similarly guided into the optical fiber 3 through reflectors 6b-6h, 7b-7h when respective shutters 8b-8h are opened. In said constitution, the connection loss between optical fibers can be made uniform and the switching time can also be made uniform.
