Abstract

The invention relates to the technical field of underwater optical communication, in particular to a deepwater underwater optical communication test system and method with a balancing weight. The optical communication transceiver unit converts an electric signal into an optical signal based on binary phase shift keying and is used for transmitting data; the optical signal amplification unit is used for receiving the optical signal transmitted by the optical communication transceiving unit and carrying out signal amplification, signal suppression and signal regeneration on the optical signal; the optical communication test unit is used for testing the performance of the underwater optical communication machine; and the ROV control unit adjusts the position of the ROV according to the USBL system data. By integrating the static performance test module and the dynamic performance test module, various performance indexes of the underwater optical communication system, including communication distance, communication rate, beam divergence angle, link stability and reliability, can be comprehensively evaluated; compared with a traditional manual test method, the method has the advantages that personal errors are reduced, and reliability and consistency of test results are guaranteed.
