Abstract

The present disclosure relates to an optoelectrical connector module comprising a flexible circuit board (10) having a first region and a second region and a printed circuit board (PCB) (20) that is attached to the first region of the flexible circuit board, and an optical module (30) that is attached to the second region of the flexible circuit board. The optical module is configured to transmit and/or receive light signals. The optoelectrical connector module comprises further a rigid support structure (40) having a first and a second surface that enclose a defined angle. The first surface of the rigid support structure is thereby arranged in parallel to the PCB and the second surface of the rigid support structure is connected to the flexible circuit board opposite the second region.
