Cable test method, device, equipment and medium

The invention discloses a cable testing method, device and equipment and a medium. The method comprises the following steps: controlling a tested cable to carry out signal transmission on a test signal for a preset number of times, and obtaining test insertion loss of the test signal in each transmission process; determining the estimated insertion loss of the test signal in each transmission process according to the measurement error corresponding to the tested cable and the test insertion loss of the test signal in each transmission process; determining reliable insertion loss and unreliable insertion loss in all the test insertion loss according to the test insertion loss and the estimated insertion loss of the test signal in each transmission process; and determining the insertion loss and the test result of the tested cable according to the reliable insertion loss. According to the embodiment of the invention, the insertion loss of the tested cable can be accurately determined according to the insertion
