摘要

The last decade has witnessed significant growth of optical communication systems due to low attenuation offered for longer distances with high capacities. Optical wireless communication such as Free space Optical (FSO) systems provide license free secure transmission with lower deployment cost to make it attractive solution for providing communication services in remote areas. However atmospheric turbulences can become major challenges for deploying the FSO systems as it affects its performance. In this work, we propose a 320 Gbps, 32 channel's hybrid fiber+FSO system using cost efficient On OFF Key modulation by incorporating hybrid dense wavelength division multiplexing scheme. Each channel carries 10 Gbps data segregated by 100 GHz channel spacing. Also, the effect of variant climatic turbulence analyzed for non-return to zero and Return to zero system considering clear sky, light fog, moderate fog and dense fog conditions.
