Optimizing Data Transmission: Analyzing FSO Based DWDM System in Turbulent Environments

There is a wide variety of network access technology available, including coaxial and copper cables, broadband radio frequency, wireless internet access, optical fibre, and many more. These technologies suffer from a number of drawbacks, including a crowded spectrum, a slower data rate, pricey license fees, and concerns over data security, and expensive installation expenses. Information may be sent via the free space optical channel using the services provided by Free Space Optics. FSO communications are gaining attention as a potential solution to the problem of a bottleneck in the last mile of a local area access network. These advantages stem from their wide data transmission capacity, cost-effectiveness in deployment, comparatively low energy use, resistance to interference, and superior degree of protection in comparison to other wireless technologies. The process of sending beams of light through the air is referred to achieve optical communication. In FSO, the optical source that is used at the transmitter is either a LED or LASER. This innovation aims at designing FSO based DWDM systems varying in number of channels and observing the effect of variation of channel length with the increase in number of channels. Moreover, different methods incorporate to mitigate the effect of turbulence.
