Radio overfree space optics (Ro-FSO) is a modern communication technique that promises a development future. In this paper, WDM Ro-FSO communication system has designed (10 Gbps×8λ) for transmissions 80 Gbps data rate via the largest possible distance under clear air, heavy rain, and heavy fog atmosphere conditions of FSO link, with test the best wavelengths performance of (193.1 to 93.8) THz that each one (wavelength) carry 10 Gbps by employ BER analyzer at receiver channels. The electric signals produced by phase shift keying (PSK) modulation technique modulated the information (10 Gbps) on RF signal (20 GHz). The results of transporting 80 Gbps were 5 km under clear air weather condition, 1.2 km under heavy rain, and 0.2 km under heavy fog condition. Finally, the different wavelengths that carry high-value data rate are tested by measurement of the BER and Q factor for each received channel, and the theoretical model of PSK modulation is analyzed.
