Abstract
A multi-input/output optical switch structure comprises a pair of parallel, inwardly facing main mirror elements 24, 25 and mounted equidistant between the main mirror elements is a co-linear array of optical switching units 40. To provide the multi-switching function and to compensate for the fact that the switch units are in a colinear array there are a plurality of additional mirror elements (41,42,43,44) mounted between the linear array and one main mirror element.
