This paper analyzes the theoretical calculation method of the characteristic impedance of copper twisted-pair transmission cable and provides the engineering basis for developing and realizing the copper transmission line based on Displayport1.1 standard. This paper shows how to maintain the consistency of characteristic impedance in the process of manufacture and manufacture of high frequency transmission line with concrete engineering examples, and then points out a clearer control method to improve the impedance characteristic of high frequency transmission line. For high-frequency cable production has a higher reference value.
