This contribution deals with estimation of rain attenuation on free space optical (FSO) links. The approximative model recommended by ITU-R is compared with the exact solution using actual rain drop size distribution (DSD) measured in Prague by 2D video-distrometer. Results show that the error is non-negligible especially at rain rates higher than 15 mm/h due to rain spectrum variability. We produced the new power law model. However, we concluded, that another parameter representing DSD must be… CONTINUE READING
