Optical fiber connector (hereinafter referred to as RF connector) is generally regarded as a component installed on a cable or installed on equipment, as a coaxial cable protective grounding or separate component. It belongs to mechatronics products. Simply speaking, it plays a key role in highway bridges.

Compared with other electronic components, the development history of RF connectors is relatively short. The UHF connector that appeared in 1930 was the first RF connector. During the Second World War, due to the urgent shortage of warfare, along with the development trend of radar detection, radio station and optical fiber communication, small and medium-sized products such as N, C, BNC, TNC, etc. were created. After 1959, SMA appeared. , SMB, SMC and other miniaturized products. In 1964, the US military specification MIL-C-39012 "General Specification for Optical Fiber Connectors" was formulated. Since then, RF connectors have just begun to develop towards standardization, generalization and practicality.

In more than sixty years, after the common struggle of authoritative experts from all over the world, the RF connector has produced a separate and detailed technical professional management system, which has become a key component of the connector family. It is an important component that the coaxial output transmission system software cannot lack. The R&D technology of RF connectors in the United States, Britain, France and other countries is at a leading level. Its design, manufacturing, testing, and application technologies have become complete and tend to be complete. Not only has it produced a detailed quality standard system, but also raw materials, auxiliary materials, Testing system software, installation special tools, etc. have also been standardized, and systematic production and manufacturing have been carried out.
