Abstract:
1. An optical communication apparatus, comprising: a PCB defining a groove in a surface thereof, the groove comprising a bottom surface substantially parallel to the surface of the PCB and a side surface connected to the bottom surface, the PCB comprising a reflecting layer coated on the side surface; a photoelectric element positioned on the PCB, the photoelectric element comprising an optical portion; a driver chip positioned on the PCB for driving the photoelectric element, the driver chip and the photoelectric element being electrically connected to each other by the PCB; and a light waveguide, an end of the light waveguide being positioned on the bottom surface of the groove; wherein an optical signal emitting/receiving direction of the photoelectric element being substantially perpendicular to the surface of the PCB, the side surface passing through a projection area of the optical portion along a direction substantially perpendicular to the surface of the PCB and inclining relative to the optical signal emitting/receiving direction for a predetermined angle, the end of the light waveguide is out of the projection area of the optical portion, and the reflecting layer reflects light between the photoelectric element and the light waveguide, thereby coupling optical signals between the photoelectric element and the light waveguide.
