Abstract
Free Space Optical (FSO) communication is being realized as an effective solution for future accessing networks, offering light passed through air. The performance of FSO system can be primarily degraded by various atmospheric attenuations such as rain, fog, haze and snow. At present, hybridization of Dense Wavelength Division Multiplexing (DWDM) with Coarse Wavelength Division Multiplexing (CWDM) becomes necessary to scale the speed and high bandwidth of the services. In this paper, primarily the attenuation values for different weather conditions are calculated. Then the hybrid WDM-FSO system is proposed, designed and the network parameters such as Bit Error Rate (BER), Quality factor (Q factor) and receiver sensitivity are analyzed with respect to link distance for various weather conditions. For investigation, four CWDM (1,510 nm, 1,530 nm, 1,570 nm and 1,570 nm) channel and eight DWDM channels (1,537.4 nm, 1,538.2 nm, 1,539 nm, 1,539.8 nm, 1,540.6 nm, 1,541.4 nm, 1,542.2 nm and 1,543 nm) are considered whose corresponding channel spacing is 20 nm and 0.8 nm, respectively. In addition, the Erbium Doped Fiber Amplifier (EDFA) is inserted at the receiver end in order to enhance the link distance. The proposed hybrid WDM-FSO system is designed to handle the quality of transmission for 12 users, each at a data rate of 2.5 Gbps along an FSO link distance of about 960 km.
