Problems solved by technology

[0004] However, the transmission speed of the existing optical transmitter module and light receiving assembly is low, and the optical transmitter module and light receiving assembly with low transmission speed are easy to couple because of their simple structure when coupling, but for the structure is more complex and There are multiple TO-CAN optical transmitter modules with faster transmission rates and optical receiving components. When coupling with conventional coupling devices, there are fewer adjustment directions and lower adjustment accuracy, resulting in the existence of multiple TO-CAN The coupling of the optical transmitter module and the optical receiving component, while using the existing coupling device, has low production efficiency, low yield, and difficult operation, which seriously affects the high transmission speed optical transmitter module and optical receiving component.
