Abstract
AbstractFree space optical (FSO) communication is a wireless communication technology in which data is transferred from one point to another through highly directed beam of light. The main factors that limit the FSO link availability is the local weather conditions. It guarantees the potential of high bandwidth capacity over unlicensed optical wavelengths. The transmission medium of FSO is atmosphere and is significantly affected by the various weather conditions such as rain, fog, snow, wind, etc. In this paper, the modulation techniques under consideration are RZ, NRZ and CSRZ. Analysis is carried out regarding Q-factor with respect to varying distance, bit rates and input laser power.
