Abstract: The invention provides an optical communications system having a dual mode o f operation. It includes a communications module having an optically active portion with a wide-angle view; a light collimator; and a connector connecting the communications module and the lig ht collimator to permit the module and collimator to be selectively positioned in a collimate d or non-collimated position. When it is in the collimated position, the communications module i s positioned at the focal point of the collimator, and, when in a non-collimated position the communications module is positioned away from the focal point of the collimator; so that the communications system has a narrow field of view when operated in the collimated position, and has a wid e field of view when operated in the non-collimated position.
