Abstract: An optical switch comprises an input array of optical elements spaced from an output array of optical elements, means to direct radiation beams and a further array of optical elements optically located between the inputs and outputs, wherein the pitch of the optical elements of said further array of optical elements is inferior to the pitch of the input and/or output array of optical elements.
Abstract: An optical connector (10) comprises at least one optical guide (12) for carrying optical radiations; a total internal reflection surface (11) upon which, in use, said radiations impinge, so that the radiation in the optical guide is reflected by said surface towards an optical element (14) of the connector and means enabling the connector (10) to interlock with any other optical connector which is appropriately matingly configured.
