Abstract
Abstract Free space optical (FSO) communication is a propitious technology and emerged as a quintessential candidate for fifth-generation (5G) networks. Inter-channel crosstalk and high cost in wavelength division multiplexed (WDM) systems are predominant limitations. Therefore, in this work, a 180 Gbps WDM-FSO system is proposed by incorporating three different states of polarizations (SOPs) as SOP 0°, SOP 45°, and SOP 90° for the first time. Moreover, the proposed system is investigated in different geographical regions of India such as hilly, desert, coastal, and plain regions. Moreover, the effects of different SOPs on the system are also evaluated in terms of the Q factor and results revealed that SOP 0° performed best in the desert region.
