Free-space optical communication (FSO) is an optical correspondence innovation that utilizations light proliferating in free space to remotely transmit information for media communications or PC organizing. “Free space” implies air, space and vacuum. FSO is a correspondence framework where free space goes about as medium amongst handsets and they ought to be in LOS (line of sight) for fruitful transmission of optical flag. Medium can be air, space, or vacuum. This framework can be utilized for correspondence reason in hours and in lesser economy. There are many points of interest of FSO like high data transfer capacity and no range permit. The transmission in FSO is subject to the medium on the grounds that the nearness of outside components like rain, mist, and murkiness, physical impediment, dispersing, and environmental turbulence are some of these variables. Distinctive examinations on climate conditions and procedures utilized to relieve their impact are talked about in this paper.
