Relay-assisted WDM-FSO System: A Better Solution for Communication under Rain and Haze Weather Conditions

54--59

Among various conventional wireless communication systems, Free Space Optics (FSO) may be distinguished as well, which provides a good level security, high data rates, an enormous bandwidth and negligible susceptibility to electromagnetic interference. The main problem arises with unfavorable weather conditions, which affect the system’s parameters and require an aversion to other paths. The weather conditions discussed are rain and haze. Elimination of their adverse effects is essential for establishing a better communication system. The routing path is a major issue, as its decreased parameters lead to the diversion of the transmitted signal or to its total loss. In this article, increased system path length and proﬁciency levels are demonstrated by using relays, which are assisted by Wavelength Division Multiplexing (WDM).
