In the recent past Free Space Optical (FSO) communication has taken over the radio frequency communication and microwave systems due to its advantages like its long-range operations devoid of need of license. In this paper we will find the most efficient transmitter suitable for free space optical (FSO) communication. The theoretical analysis of behaviour of an FSO wireless communications system is done using on off keying with different transmitters over fog weather conditions. Based on different models for optical beam propagation at 1550nm and 10000nm on an FSO, the bit error rate (BER) and Q-factor under fog weather are analyzed.
