Challenges in Free Space Optical Communication.

      Аннотация: This report proposes a communication system related to free space which work on high bit rate. In optical network there is main advantage it make the communication so easy and effective.in this paper the main goal is it provide large bandwidth along with high data transmission via a communicating link. There is no process or system which has no challenges, here the major challenge is atmospheric disturbances which causes the improvement in bit error rate and reduces the data speed. In this book, the goal is to reduce these effects and makes it more efficient. After analyzing this high speed communication link designing a FSO related application and provide high data rate. In this book, efforts have been made to mitigate or to minimize the effects of scintillation by evaluating the performance of the system through simulation.The main advantage of utilizing this techniques is to increase the range of the communication system which is normally not too high it is more then in kilometers. But after utilizing this technique it gives efficient free space communication.
