Abstract
An optical switch includes a plurality of optical fibers arrayed at equal intervals and in parallel, each optical fiber having a central axis and having an end surface on one side of the optical switch. A single lens has a focal length and a central axis parallel to each fiber central axis, the lens disposed away from the fiber end surface at a distance corresponding to the focal length of the lens. A first mirror has a reflection surface perpendicular to the lens central axis, the first mirror removably disposed at a first position on the other side of the optical switch. A second mirror has a reflection surface inclined from the lens central axis, the second mirror removably disposed at the first position. One of the first and second mirrors is selectively disposed at the first position.
