Photoelectric module and preparation method thereof

The invention discloses a photoelectric module and a preparation method thereof, and the method comprises the steps: arranging an electric connection surface and an optical coupling surface on a single PCB at an interval, respectively preparing the electric connection surface and the optical coupling surface, carrying out the bonding of an electric contact, completing the installation of a photoelectric coupler, carrying out the additional testing steps, and carrying out the cutting to prepare a plurality of PCB units. And a corresponding photoelectric module is further prepared. A plurality of photoelectric modules can be prepared at the same time, and the assembly efficiency is improved; the aging of a plurality of photoelectric modules can be completed at a time, the requirement for a test jig is reduced, the plurality of photoelectric modules can be tested in batches, and the test efficiency is high; the test fixture controls the photoelectric module to emit light, and the test method is simple; the assem
