An optical switch (1) for switching light beams between one input optical fiber (21) and a plurality of output optical fibers (31) has a first port (2), a second port (3) and a switching element (4) between the first and second ports. The input port aligns with the input optical fiber and collimates input light beams. The output port aligns with the output fibers and decollimates output light beams. The switching element includes at least one rotatable optical element (41) for deflecting the light beams and a holder (42) for containing the rotatable optical elements. The rotatable optical element is rotatable among a plurality of positions, whereby, when the optical element is in different positions, the light beams from the input optical fiber are switched to different output fibers, respectively.
