Perspective Methods of Transferring Information Via Optical Communication Channels

Perspective methods of information transfer in optical communication channels based on the latest achievements of quantum physics are considered. In the near future, these methods can solve both the problem of creating an optical channel conducting with physically unlimited bandwidth, and the problem of secretly transferring information in a fiber-optic information channel. The results of the latest experiments related to the quantum properties of photons are described. The use of solitons as carriers of an information signal is considered. The technologies of using the ‘temporal cloak' and noise of optical amplifiers for data transmission in fiber-optic communication lines are presented.     Keywords: optical steganography, soliton, optical fibe
