Research on test methods for high-speed transmission cables

With the rapid development of aerospace technology and the need for high-speed data transmission, the high-speed cable industry is gradually maturing. However, in the aerospace field, there is no definite method and special equipment for its testing. This paper analyzes the necessity of high-speed cable testing research in aerospace field by studying the current cable testing methods and equipment in aerospace and other fields. Based on the summary of the basic theory and technical requirements of high-speed transmission cables, test equipment and test methods applicable to high-speed transmission cables in the aerospace system are studied, and their test parameters are cut and rounded according to their importance and impact on signal transmission. Through the research and summary of the system theory and test methods, it provides a guide for testing high-speed transmission cables in the aerospace field to meet the testing needs in the production and application of high-speed cables in the aerospace system.
