The application provides a connector device for connecting at least one optical fiber endpiece to an electric terminal. The connector device comprises a printed circuit board and an electric connector plug connectable to an electric terminal. A fiber end piece holder is mounted or mountable in an orientation enabling light propagation parallel to the printed circuit board, whereas an optoelectronic chip comprising optoelectronic active elements enables emission and/or detection of light substantially normal to the printed circuit board. A layered optical stack is provided on the printed circuit board, which layered optical stack comprises a reflection surface for changing the propagation direction between parallel and normal to the printed circuit board.
