A rotatable mirror optical switch arrangement (100) comprising: an input array of light sources (160); an output array of light receivers (180); a first rotatable platter (110) of mirror elements arranged between the input array and the output array whereby light (140, 150) from a desired one of the input array of light sources is reflected via the rotatable platter to a desired one of the output array of light receivers dependent on rotation of the first rotatable platter. The mirror elements may be comprised in a free-form surface. The size of a single mirror may be smaller than 1 mm². A passive optical switch matrix (275) may be positioned between the input and output arrays to increase switching permutations. The mirror elements may be arranged in segments (100), which may be arranged in sectors and rings.
