Free-space optical link for terrestrial communication greatly depends on environmental conditions. Varying climatic conditions across regions cause turbulence on the deployed FSO link, which inherently affect its performance. Various techniques have been introduced to mitigate these effects. This paper provides the study on wavelength diversity technique, in which FSO link is established with two optical channels of wavelength 532 and 1350 nm, to understand its performance under varying climatic conditions. Either channel gets selected dynamically based on attenuation levels. Observations are recorded under fog and clear atmosphere. Also, experiments have been performed to understand the effect of distance variation on FSO link under clear atmosphere.
