Claims

[Scope of utility model registration request]

It comprises two sets of optical elements in which a plurality of optical fibers are optically coupled at their ends, and means for switching the optical coupling state between the coupling ends of the two sets of optical elements, and the switching means A first state in which the coupling ends of the optical elements of the set are optically coupled to each other; and a first state in which the optical coupling between the coupling ends is interrupted and the incident light from one optical fiber is transmitted to the same optical element at each coupling end. An optical switch characterized in that it switches between a second state in which the light is reflected onto another optical fiber.
