Abstract
Over the past several years, there has been a renewed interest in Free Space Optical (FSO) communication technology, commonly referred to as Optical Wireless Communications (OWC). FSO is sometimes viewed as a substitute for current technology, such radio frequency. In other situations, FSO is viewed as a potent contender to work in tandem and complement next-generation technology, such 5G wireless networks. FSO technology is therefore widely used in a variety of indoor (such as data centers), terrestrial (such as mobile networks), space (such as intersatellite and deep space communication), and underwater systems (such as underwater sensing). Nevertheless, despite the enormous potential of FSO communication, unfavorable effects (such as absorption, scattering, and turbulence) limit its performance. Of these three effects, atmospheric turbulence poses the greatest threat since it might seriously impair the system's bit error rate (BER) performance and render the communication link unworkable. The first part of this paper presents a semi complete survey on various challenges faced by FSO communication system for both terrestrial and space links. The second provides details of various performance mitigation techniques in order to have high link availability and reliability of FSO system. The third provides the classification frameworks because the necessity for a precise classifications of FSO connection configurations increases with the expansion of the application portfolio for FSO technology. The fourth and final, it talks about standards and recommendation for free space optical communications.
