“…The minimum simulation report of BER has been reported as 10 −9 under diverse climate conditions [12]. Paliwal et al 2021 authors have investigated 4 channels WDM−FSO system with a 2.5 GB/s data rate at a 25 km link range by using NRZ modulation format. This research has also perceived that an erbium−doped fiber (EDF) amplifier can be used to overcome the effect of attenuation [20].…”

This paper is successfully demonstrating simulating comparison and investigation of 48 channels of dense wavelength division multiplexing free space optical (DWDM−FSO) network with a 10 GB/s data rate on each channel separated by 100 GHz frequency spacing under a clear sky, haze and light rain climate conditions. Apart from this, comparison of a series of modulation formats such as non−return to zero (NRZ), return to zero (RZ), carrier suppressed return to zero (CSRZ), Soliton pulse, and offset quadrature phase shift keying (OQPSK) have been performed and optimized the performance of the designed system with best suited modulated system. The performance of the proposed work has been evaluated in terms of bit error rate (BER), quality factor (Q), signal−to−noise ratio (SNR), received signal power and eye diagrams. It has been observed that OQPSK modulated system has shown more robust performance as compared to other line encoding techniques. The minimum simulation work reports for OQPSK modulated system have been recorded with the acceptable performance BER ≤ 10−10, Q ≥ 6 dB at the 2000 meters FSO link range.

Gigabit - per - second data speeds can be achieved via free space optics (FSO) lines, which needless system complexity. On the other hand, the link's availability across a wide range of atmospheric circumstances is a major worry. As a result of the increased signal attenuation caused by the linkages being weather - dependent, their efficiency decreases. Up to 70 dB/km of attenuation can be caused by bad weather on a 500 - meter free space optics link. In this work, transmission windows of 1310 nm, 850 nm , and 1550 nm are analyzed and compared using the free space optics link. by using the Simulation program o pti system such as the q uality factor, the minimal bit error rate (BER), and the e ye diagram is taken into account. Analyzer findings are compared to establish the optimal wavelength for a transmitter under poor weather conditions.
