ABSTRACT

Special features of construction of fiber-optical transmission systems with amplitude and phase manipulation of optical signals are considered. Methods for a comparative assessment of the information protection are presented. The obtained results are analyzed. The need and the expediency of implementation of signal phase manipulation on fiber-optical transmission systems at the contemporary stage are estimated. Conclusions are formulated.
