Abstract
The underwater wireless optical communication (UWOC) system gives very high rate of underwater data transmission over several meters. It utilizes the visible band in the spectral range of 390-750nm of the electromagnetic spectrum. In this paper, we study various types of link configurations depending upon the circumstances in water environment. We also study the effect of various water types on the system performance. We find that the UWOC system is affected especially by inherent optical properties such as absorption and scattering and the effect of these properties is different in various water types. We also present that misalignment in UOWC system adversely affects its functioning and reliability. Finally, we present that hybrid system design for a proper systematic UOWC system.

Summary
The increase in global warming and reduction of ground has increased the exploration of ocean. The Underwater wireless communication (UWC) technology can achieve the exploration of ocean. The underwater wireless communication is define as the transmission of data in a random water medium with the use of wireless carriers like radio-frequency (RF) waves, acoustic waves, and optical waves [1]. Because of the restricted bandwidth of radio-frequency (RF) and acoustic system and the requirement of high speed underwater data transmission rate underwater wireless optical communication (UWOC) is needed [2]. Underwater wireless optical communication (UWOC) is the transmission of data in a random water medium with the use of optical waves. The Primary Underwater wireless sensor network (UWSN) comprise of a large number of Distributed nodes such as Seabed sensors, relay buoys, autonomous underwater vehicles (AUV) and remotely operated underwater vehicles (ROV).In figure 1,sensors situated in the depth of the seabed gather the data and transmit it via optical link to AUV and ROV. The ground data centre process the data and communicates with satellite and ships through RF or FSO link
