Abstract


ABSTRACT
Free Space Optical (FSO) communication technology, widely known as optical wireless system is a upcoming and most economical communication system along with high data rate and numerous advantage over conventional RF wireless communication system. RF wireless communication system has numerous number of restriction which is overcome by Free space optical communication system for example bandwidth limitation or spectrum issue is major challenges in conventional RF wireless communication system but in Free space optical communication system offer high bandwidth where licensing of spectrum does not require due to high bandwidth [1] [2]. At times, FSO is viewed as an option in contrast to existing advancements, for example, radio recurrence. In different cases, FSO is considered as a solid contender to supplement and coordinate with cutting edge advancements, for example, 5G remote systems. As needs be, FSO innovation is in effect broadly conveyed in different indoor (e.g., server farms), earthly (e.g., portable systems), space (e.g., entomb satellite and profound space correspondence), and submerged frameworks (e.g., submerged detecting). As the application arrangement of FSO innovation develops, so does the requirement for an unmistakable grouping for FSO interface setups most existing studies and characterizations are single-level orders, and in this way not comprehensive enough to suit later and rising changes and improvements of various FSO connect designs and frameworks. In this paper, we propose a staggered grouping structure to arrange existing and future indoor, earthbound, space, submerged, and heterogeneous FSO connections and frameworks utilizing normal and straightforward bound together documentation. We utilize the proposed order to audit and condense [3] [4]. At times, FSO is viewed as an option in contrast to existing advancements, for example, radio recurrence.
