Abstract

This study presents the analysis of a designed Ro-FSO system by Opti System v.20. The system analysis depends on transferring three values of data (10, 20, and 40 Gb/s) using two digital modulators (PSK and DPSK). Two scintillation systems (L-N and G-G) are applied for transmitting a signal through free space; this signal is subject to four values of atmospheric turbulence. The research showed that the (L-N) scintillation model can send data at rates of 10, 20, or 40 Gb/s, irrespective of what kind of digital modulator is used. For data rates of 10 and 20 Gb/s, the suggested system could transmit it over a maximum link distance of up to 2 km under different turbulence intensities. For 40 Gb/s of data rate, the maximum link distances decline to 1.75 km at the same amount of turbulence conditions. When the scintillation system (G-G) is applied as a turbulence link, the system is able to transmit the signal well for a maximum link distance not exceeding 0.75 km.
