AI Technical Summary

Problems solved by technology

The socket and plug in the traditional fiber optic connector are respectively provided with a fiber guide hole for accommodating the optical fiber and a lens for collimating or concentrating the optical signal transmitted by the optical fiber. However, since both the socket and the plug are injection molded The manufacturing process is integrally formed. If the center of the guide hole and the optical axis of the lens cannot be aligned accurately, the center of the optical fiber in the guide hole will not be aligned with the optical axis of the lens, which will easily cause optical signal loss and reduce the optical fiber.
