Abstract

The invention discloses a photoelectric conversion module. The photoelectric conversion module comprises a circuit board, a plane light waveguide which is formed on the circuit board, first and second lenses which are arranged above the plane light waveguide, a substrate which is electrically connected with the circuit board, a laser element and a light receiving element, wherein the laser element and the light receiving element are arranged on the substrate. A slant surface is formed on the plane light waveguide. The substrate is located above the second lens. The first lens, the second lens, the slant surface, the laser element and the light receiving element are aligned. A light signal of the plane light waveguide is reflected to the first lens through the slant surface, is transmitted to the light receiving element through the second lens, and is converted into an electric signal, and the electric signal is transmitted to the circuit board. The laser element converts the electric signal of the circuit board into a light signal, and the light signal is transmitted to the plane light waveguide through the second lens, the first lens and the slant surface. The invention further provides a light transmission connection component. In the photoelectric conversion module, the plane light waveguide is formed on the circuit board. The first lens and the second lens are arranged between the substrate and the circuit board through a first mounting member and a second mounting member. The assembly is simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to an optical transmission connection assembly, in particular to an optical transmission connection assembly for converting and transmitting optical signals and a photoelectric conversion module used therein. Background technique [0002] In recent years, optical communication has the development trend of high speed and large capacity. When the existing photoelectric conversion module is packaged, silver glue is used to fix the laser element and photodetector element on the circuit board, and UV glue is used to fix the plastic outer cover on the circuit board, so that the outer cover covers the laser element and the light-receiving element. , the optical waveguide is inserted into the outer cover. Due to the complicated design of optical components, it is difficult to realize automatic assembly. Therefore, most of the optical components are currently assembled manually. However, the complicated manual work increases the manufact...
