Underwater optical wireless communication system supplies extraordinary enthusiasm to the military, industry, and mainstream researchers, as it assumes a significant job in strategic observation, contamination checking, oil control and upkeep, seaward investigations, environmental change seeing, and oceanography research. To encourage every one of these exercises, there is an expansion in the quantity of unmanned vehicles or gadgets conveyed submerged, which require high data transmission and high limit with regards to data move submerged. Even if massive advancement has been made in the field of acoustic correspondence submerged, be that as it may, it is restricted by data transfer ability. This has prompted the expansion of underwater optical wireless communication system as it gives higher information rates than the customary acoustic correspondence frameworks with fundamentally lower power use and less difficult computational complexities for short-extend remote connections. Underwater optical wireless communication has numerous potential applications running from profound seas to beach front waters. Be that as it may, the greatest test for underwater optical wireless communication system from the principal attributes of sea or ocean water. Tending to these difficulties requires an exhaustive comprehension of complex physic-compound natural frameworks. This paper gives a comprehensive outline of ongoing advances in underwater optical wireless communication. Channel representation, parameter plans, suitable wavelength of underwater optical wireless communication, light used for optical communication, various noise sources, analysis of received and transmitted power are discussed for to underwater optical wireless communication. This paper not just gives comprehensive examination in underwater optical wireless communication system in addition intends to give the improvement of new thoughts that would help in the development of future underwater optical wireless communication.
