Abstract

Free space optics (FSO) has regained considerable attention over the years due to higher data rate transmission capability and unlicensed bandwidths. Nevertheless, different atmospheric conditions result in the considerable deterioration of the performance of the link. The performance of MDM-WDM based FSO link has been analysed considering LP 00 and 01 modes employing AMI, NRZ and RZ modulation techniques. The system has been designed to transmit information at a data rate of 80 Gbps upto a transmission range of 6 kms under clear air conditions. The maximum transmission range under heavy fog and rain conditions reduces to 900 m and 950 m respectively.
