•Performance of OAM-based FSO over realistic FSO link is analyzed.•Comparison is made between realistic Pump and simplest Kolmogorov models.•Higher channel capacity is projected when the realistic Pump spectrum is used.•Pump model is much more appropriate in any analysis of OAM-based FSO systems.
We study the influence of atmospheric turbulence on OAM-based free-space optical (FSO) communication by using the Pump turbulence spectrum model which accurately characterizes the realistic FSO link. A comprehensive comparison is made between the Pump and Kolmogorov spectrum models with respect to the turbulence impact. The calculated results show that obtained turbulence-induced crosstalk is lower, which means that a higher channel capacity is projected when the realistic Pump spectrum is used instead of the Kolmogorov spectrum. We believe that our results prove that performance of practical OAM-based FSO is better than one predicted by using the original Kolmogorov turbulence model.
