Free Space Optical Communication (FSO) is the communication system which uses optical signal to establish a direct link between two points. With increase in the use of digital data and requirement of high speed communication it has become necessary that the reliable and high speed communication system should be developed in order to provide uninterrupted service. Use of wireless signals in every type of communication has crowded the space and often results in increased interference. These all issues can be solved with the development of an efficient FSO. This paper focuses on the development an efficient FSO system for short range communication purpose using multi-laser beams and efficiency of FSO network under different weather conditions. © Research India Publications.
