A coupling element is provided for connecting an electrical apparatus to an optical data bus with a unidirectional transmission. A housing contains an opto-electrical transducer to which an input data bus line is optically connected, an electro-optical transducer to which an output data bus line is optically connected, and two electrical contacts on an exterior side, by way of which the two transducers can be electrically connected with the electrical apparatus. A switchable electrical connection is provided between the two transducers which, when the electrical apparatus is connected, is open and, when the apparatus is not connected, is closed. |
