Original Paper


Free space optical transmission has a wide area of applications in the field of digital services. It has special features such as low maintenance cost, licence-free and less deployment time. It is a solution to replace optical fiber cable for providing services in rural area. In this paper, the performance of the two independent channels LP01 and LP11 by mode-division multiplexing over free space optical (FSO) link is investigated. Each channel carries data at 10 Gbps data rate, and the data are transmitted over 8 km FSO link with NRZ/RZ encoding schemes. The performance of the MDM-FSO system is evaluated under atmospheric turbulences which gives better results in RZ encoding scheme as compared to NRZ scheme at acceptable level of SNR and BER.
