FIBRE-OPTIC SOLITONIC SYSTEM FOR SYNCHRONOUS DIGITAL CHANNEL TRANSMISSION Russian patent published in 2016 - IPC H04J14/08 

Abstract RU 2574338 C1

FIELD: radio engineering, communication.

SUBSTANCE: invention employs polychromatic solitonic pulses generated by radiators of transmitting equipment with a frequency equal to the clock frequency of input digital streams of the system, which are then modulated by channel signals and, using fixed optical delay lines and adding a synchronisation channel soliton, a clock frame of a linear system signal is generated. The said signal is fed into a linear channel after necessary amplification. At the receiving end of the line after optical pre-amplification, polychromatic solitons of the group signal are distributed by a spectral demultiplexer between same-type temporal demultiplexers of a multistage structure, the operation of which is controlled by a receiving synchronisation unit which is timed by the received system synchronisation channel soliton.

EFFECT: high noise-immunity of the system and high stability of the operation of the system and volume of transmitted information.
