Abstract: An optical relay device includes a substrate, and a first transmission module and a second transmission module that are provided on the substrate. The substrate has a first side and a second side opposite to each other in a direction perpendicular to the substrate. The first transmission module and the second transmission module both include at least one light emitting unit and at least one light receiving unit. The light emitting unit includes at least one light emitter. The light receiving unit includes at least one light receiver. Optical paths of light receiving units and optical paths of light emitting units are provided in one-to-one correspondence in the direction perpendicular to the substrate, and the light receiving unit and the light emitting unit that are corresponding to each other form a signal transmission channel.
