摘要：Today Free-Space Optical communication (FSO)has overcome the radio frequency communication. Thispaper gives an overview of the availability of an FSO system and its different weather conditions. It describes problemsthat the designer faces while implementing an FSO system and to overcome that problems .Performance analysis of asystem for different weather conditions is carried out. Calculation of attenuation due to fog by using KIM and KRUZEModel and other parameters such as received power, BER and Q factor are analyzed. FSO provides data rate upto 1 gbps. A laser diode at the transmittter side of 850nm and the PIN diode as a photodetector at the receiver side is used. It ispossible to calculate visibility from the measured data which is the main factor for estimation the availability andreliability of FSO link . The system link is established using simulation software optisystem and system characteristics isstudied.
