Investigations on Free space optics communication system

In this paper we improve the quality of free space optics (FSO) communication system. With the current needs of this technology for longer distance, the qualitative analysis of the system has become essential. In this work, the received power level (PR) and bit error rate (BER) are considered to determine the fso link performance. The relationship between the two parameters are investigated and analyzed. Then the received power for various number of TXs and RXs are experimentally measured and compared with the theoretical value calculated. The work deals with the theoretical calculation and simulation designs of the multiple laser beams based on the commercial FSO on the practical site.
