Test setup: Input test instructions to the system through the remote control function of the control module to control the signal generation module to generate electrical and optical signals of different frequencies, amplitudes and waveforms; S3, signal transmission and reception: The signal sent by the signal generating module is transmitted through the cable to be tested, and the signal receiving module and the signal analyzing module receive the transmitted signal, and measure and analyze the insertion loss, return loss, differential return loss, differential impedance, skew and delay; S4, data processing and result presentation: The signal receiving module and the signal analysis module transmit the measurement data to the data processing module, which processes the data according to the preset standards and algorithms, calculates the test results, and generates a test report and a test result code. The test status and performance indicators of the cable are intuitively displayed through the data display module; S5. End of test and cleaning: After the test is completed, remove the cables to be tested, clean the fixture module and the port module, close the system, and then push the port module (3) into the storage chamber (13), thereby releasing the closing curtain (2).

9. A computer device comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that: When the processor executes the computer program, the testing method of a high-speed cable testing system as claimed in claim 8 is implemented.

10. A readable storage medium, characterized in that: The readable storage medium stores a computer program, and when the computer program is executed by the processor, the test method of the high-speed cable test system according to claim 8 is implemented.
