The research progress in underwater wireless optical communication technology

Underwater wireless optical communication, which is an effective technical way to build a high-speed and flexible underwater wireless communication network due to its large bandwidth, good confidentiality and low time delay, is widely regarded as a complementary communication way to hydroacoustic communication. The newest research progress and main technical specification in the current technology of underwater wireless optical communication are introduced, the characteristics of the current underwater wireless optical communication technology are summarized in this paper. A series of improvement measures are proposed for the problems of short communication distance and low robustness in underwater wireless optical communication system, which can provide references for underwater wireless optical communication technology research and engineering project development.
