DATA THroughput OF OPTIC FIBERin quantum communications system

Abstract

A mathematical model of communications channel that transfers data by means of separate photons having different polarization has been developed. The expression for calculating of optic fiber throughput has been obtained that takes into account probabilities of depolarization and absorption of radiation photon. As a result of implemented simulation it has been found that data throughput depends on the length of optic fiber. It has been established that photon absorption as compared with its depolarization contributes greatly to the size of optic fiber throughput.
