Provided are a single-fiber bidirectional multimode WDM optical-to-electrical converter and a fabrication method thereof. The converter includes: a PCBA, a deflection lens module, a WDM module, and a second collimation lens. The PCBA has an electrical connector, an optical fiber connector, first positioning portions, a plurality of lasers, and a plurality of photodiodes. The deflection lens module has a light incident surface, a reflecting surface, a light emergent surface, and first fitting portions. The deflection lens module is mounted on the PCBA through engagement of the first fitting portions and the first positioning portions, and a plurality of first collimation lenses is aligned with the plurality of lasers and the plurality of photodiodes. The fabrication method includes: mounting lasers and photodiodes on a PCB with respect to first positioning portions on the PCB; and mounting a deflection lens module on the PCB through the first positioning portions. 1.
