Abstract:
An arrangement in an electro-optic circuit that includes optical sender components for transforming an electrical output signal to an outgoing optical signal and optical receiver components for transforming a received optical signal to an electrical input signal, connection means for an optical conductor on which the outgoing and received optical signals are transmitted, a sender for the electrical output signal, and a receiver for the electrical input signal, the arrangement comprising:a module with an electromagnetically shielded housing that contains the optical sender and receiver components and the connection means, and a two-sided printed circuit arrangement that is located between a lower portion and an upper portion of the housing and that carries the sender and the receiver on one side each shielded from each other by an electrically conducting shielding that is in connection with the housing for forming three Faraday's cages, one for the sender, one for the receiver and one formed of the housing in its entirety; andcontact means between the housing and grounding portions of the printed circuit card arrangement, the shielding between the sender and the receiver, and an outer printed circuit card on which the module is attachable, wherein the contact means comprises a number of longitudinal spring means along insides of the housing lower and upper portions, and each spring means is shaped in one piece and has a number of contact points for the printed circuit card arrangement, a number of contact points for the lower portion, a number of contact points for the upper portion, and a number of contact points for the outer printed circuit card.
