ABSTRACT:
An electro-optical circuit includes optical sending and receiving components for transforming an electrical output signal to an optical output signal, and for transforming a received optical signal to an electrical input signal, respectively. The electro-optical circuit forms a module with an electro magnetically shielded case which contains the optical sending and receiving components and connection devices for an optical conductor on which the outgoing and received optical signals are transmitted. A two-sided printed circuit arrangement carries a sender for the electrical output signal and a receiver for the electrical input signal located shielded from each other on one side each by means of an electrically conducting shielding. The shielding is in connection with the case for forming three Faraday's cages, one for the sender, one for the receiver and one formed of the case in its entirety.
