Light coupling adapter, method, device and electronic equipment

The invention relates to the technical field of optical communication, in particular to a light coupling adapter, method and device and electronic equipment. The light adapter comprises a light receiving module and a fixing module, the fixing module is used for fixing the light receiving module, the light receiving module comprises a light receiving unit and a coupling unit, the coupling unit is installed on the optical fiber end face of the light receiving unit, and when the light receiving module receives light, coupling parameters corresponding to the coupling unit correspond to the incident angle of the light. On the basis of the adapter, the coupling parameter corresponding to the incident angle of the incident light is configured, so that the adapter can be suitable for application scenes with relatively large incident angles, and the light coupling efficiency is improved. Meanwhile, since the coupling unit is directly connected with the optical fiber end face, the installation difficulty can be reduced
