Description
  • In the paper, the availability of free space optics (FSO) systems in dependence on weather conditions and on link parameters such as transmitted optical power, beam divergence, link path distance or receiver sensitivity is discussed. A number of phenomena in the atmosphere such as scattering, absorption and turbulence can affect beam attenuation, but in the case of wavelengths typical for FSO systems operation only turbulence and scattering are appropriate to be taken into consideration. Attenuation due to scattering can be expressed as a function of the link distance, wavelength and meteorological visibility. The atmospheric attenuation and consequently FSO availability were calculated by using actual visibility data collected at several airports in Europe.

  • V publikaci se řeší dostupnost bezkabelových optických spojů v závislosti na povětrnostních podmínkách a parametrech spoje jako například svysílaný optický výkon , divergence svazku, délka spoje nebo citlivost přijímače. Řada jevů v atmosféře jako rozptyl, absorbce nebo turbulence mohou ovlinit šíření svazku ale v případě vlnových délek typických pro bezkabelové optické spoje má smysl uvažovat jen turbulenci a rozptyl .Útlum vlivem rozptylu může být vyjádřen jako funkce meteorologické viditelnosti. Útlum atmosféray a následně dostupnost bezkabelových optických spojů jsou počítány ze záznamů viditelnosti na několika letištích v Evropě. (cs)
