| Abstract. The presented topic examines the immense potential of Free Space Optics (FSO) applications and explores the impacts of varying environmental parameters on FSO's effectiveness, depending on the near-infrared wavelength range used. During the transmission phase, optical signals in the transmitter environment undergo extinction and attenuation, while changes in the environment's turbulent nature affect the transmitted and received optical signal parameters. The aforementioned atmospheric influences heavily impact the signal-to-noise ratio, which serves as a quality indicator of the optical channel and the likelihood of transmission channel bit errors. The results of the research conducted at 1.31 μm, 1.55 μm, and 1.62 μm wavelengths used in the formation of optical channels between inter-peak, peak-place, place-peak, and ground terminals are given in the article. By using optical compression systems based on the spectrum in FSO and considering the number of optical channels organized by multiplexing N_k, frequency efficiency η_SE (λ_i), quality factor Q_F, and error probability per bit P_BERare investigated to achieve maximum transmission speed SNR(P_S) while minimizing the signal-to-noise ratio. |
