USING OF SINGLE-QUANTUM REGISTRATION FOR CONFIDENTIAL INFORMATION TRANSMISSION SYSTEMS OVER FIBER-OPTIC COMMUNICATION LINES

Abstract

The system for transmission and reception of confidential information over fiber-optic communication line on the basis of created single-quantum registration system of optical radiation has 43 been suggested. With regard to such a communication system two types of optical wavelengths have been experimentally justified. One type of optical wavelength is used for information transfer and the second one for time synchronization of information transmission and reception, as well as for detection of unauthorized access to information, created with optical fiber macrobends. Optimal values of optical power, which allowed to provide the highest confidential information data rate and detect more effectively possible data loss channels have been established.
