In this paper, we present an implemented serial 40‐Gb/s receiver optical subassembly (ROSA) module by employing a proposed TO‐CAN package and flexible printed circuit board (FPCB). The TO‐CAN package employs an L‐shaped metal support to provide a straight line signal path between the TO‐CAN package and the FPCB. In addition, the FPCB incorporates a signal line with an open stub to alleviate signal distortion owing to an impedance mismatch generated from the soldering pad attached to the main circuit board. The receiver sensitivity of the ROSA module measures below –9 dBm for 40 Gb/s at an extinction ratio of 7 dB and a bit error rate of 10 −12 .
