Atmospheric turbulence on FSO at 785 nm

Abstract

The atmospheric turbulence is one of the cause of channel impairments of the free space optical links. This phenomenon appears even in case of clear sky conditions and according to the literature it may affect the availability of the connection. In this paper the atmospheric turbulence will be studied, based on longterm measurement data. The measurements were performed on a 930m long free space optical link that operates at 785 nm wavelength.
