Abstract

The transceiver module has the transmitter and receiver mounted on one side of a leadframe above light passage openings formed therein. A beam deflection receptacle, containing a fiber connection opening, at least one beam splitter and a deflection mirror, is fixed on the other side of the lead frame. The external electrical terminals of the leadframe are bent around a plastic covering and shaped out to form terminal areas, so that the module is suitable for SMT.
