This case relates to a connector, especially a connector with an optical fiber connection device and a connector set.

Optical fiber communication refers to a way of using light and optical fibers to transmit information, which is a kind of wired communication. Light can carry information after being modulated. Due to the advantages of large transmission capacity and good confidentiality, optical fiber communication has gradually become the mainstream wired communication method in recent years, and also plays an extremely important role in the industry.

With the advancement of computer technology and the rapid development of the Internet, the demand for electricity has also risen sharply. In order to provide sufficient power, a plurality of power modules are often configured in the power system cabinet, and most of them are medium-voltage power modules. Since the system control area of the central controller is a low-voltage area, the transmission of signals in the medium-voltage area and the low-voltage area will be restricted by safety regulations. Therefore, the common practice in the industry is to transmit some signals by optical fiber communication to avoid related safe question.

However, there are still shortcomings in the traditional connection method between the medium voltage power module and the optical fiber cable. Please refer to FIG. 1 , which is a schematic diagram showing the connection between a traditional medium voltage power module and an optical fiber cable at the system end.
