“…To meet the demand of services, there is a huge requirement of bandwidth; WDM-FSO is the leading and well-known technique for broadband transmission (Singh and Saini 2014). But apart from these bene ts, WDM has its own set of drawbacks such as high operation cost and higher complexity (Saini and Wason 2019; Malik and Singh 2015; Singh et al 2012). To nd a solution to these limitations, spectrum slicing technology is used over the WDM, where the spectrum slicing technique has an operation that does have less complexity when compared with WDM (Nor et al 2011).…”

Over the last decades, free-space optics (FSO) emerged as a prominent way of communication over radio frequency communication and microwave communication. Working of FSO in comparison with optical ber cable (OFC) network is the same. The only difference between FSO & OFC is the transmission of an optical beam. The optical beam is transmitted through the free space in the case of FSO. Whereas the transmission of optical beam takes place using OFC core, i.e. glass ber in the case of OFC. Fog, haze, rain, and clouds in the atmosphere directly affect FSO performance and the power of signal propagation.Further added, the wavelength of propagating beam is based on the size of fog particles which leads to atmospheric attenuation. To mitigate the impact of atmospheric attenuation on signals, the proposed study is based on a spectrum slicing (SS) -wavelength division multiplexing (WDM) system with Pre and Post Ampli cation. The analysis of SS-WDM-Pre and SS-WDM-Post has been done over various values of attenuation. The comparison analysis proves that the SS-WDM-Post is more e cient than both SS-WDM-Pre and traditional SS-WDM in terms of Q-factor.
