Abstract
Each of light beam switching elements disposed between input and output fiber collimators includes a support member, a first reflection member mounted on the peripheral portion of the support member and a second reflection member mounted on the peripheral portion of the support member. The first reflection member has a first reflection mirror surface to reflect the light beam from the input fiber collimator, and the second reflection member has a second reflection mirror surface to reflect the light beam reflected by the first reflection mirror surface. A drive actuator allows each of the switching elements to assume a first rotation position in which the light beam from the input fiber collimator is reflected by the first and second mirror surfaces, and a second rotation position in which the light beam from the input fiber collimator passes between the first and second reflection members without being reflected by the mirror surfaces.
