The connector device comprises a layered optical stack mounted to the circuit board and designed for propagation of optical signals along the first propagation direction. The connector device further comprises a coupling adapter piece mounted to the layered optical stack that holds and/or secures the fiber end piece holder in an orientation enabling propagation of signals radiation along the second propagation direction. The reflection surface for changing between both propagation directions is comprised in the coupling adapter piece.
