Underwater wireless communication technologies can transmit data by utilizing different types of waves such as sound, radio, and optical. However, audio and radio waves have their bandwidth limitations, which means they cannot transmit as much information as quickly as optical waves can. In contrast, underwater optical communication can transmit a massive amount of data with very low latency. Underwater wireless communication can transmit information using sound, radio and optical waves. Comparisons indicate that there is a bandwidth limitation in audio and radio waves, while underwater optical communication can transmit a very large amount of information with very little delay. However, water bed conditions (e.g. absorption, scattering, turbulence, etc.) pose great challenges for this type of communication and significantly reduce the achievable communication range. To solve these problems, efficient networks and solutions in the field of equipment placement and localization are needed. Also, choosing the right parts, including laser, diode, and photodiode, can significantly increase the performance of the system. Another existing problem is the low range of underwater optical communication, which can be avoided by designing a suitable network. A underwater optical communication network system was designed and built for this research using electronic circuits, optical transmitters, and receivers. The system is capable of transmitting various types of information, including audio and video. The first step was to simulate and design the circuit. Afterward, the circuits were practically built, tested and examined in an aquatic environment (aquarium).In this research, using electronic circuits and the use of optical transmitters and receivers, a submarine optical communication network system was designed and built, which can partially meet the needs of sending different information such as audio and video. First, for this work, simulation was done and the circuit was designed, then the circuits were practically built and examined and tested in the aquatic environment (aquarium).
