Estimation of FSO Link Availability in Central European Localities

摘要

The estimation of FSO link availability is based on synthesis of two models: the steady model of given link and the statistical model of installation site. The steady model consists in the knowledge of FSO transceiver parameters so that we can compute the power budget for a given transceiver distance. The result is the dependence of link margin on the transceiver distance. The statistical model consists in the knowledge of statistical parameters of atmosphere at given installation site. The installation site is described by the exceedance probability of atmospheric attenuation. By means of synthesis of both models we can obtain estimation of link availability. In this contribution, estimation of FSO link availability in chosen Central - European localities is presented.
