SYSTEM FOR TRANSMITTING INFORMATION IN REAL TIME BASED ON A FULLY OPTICAL SPECTRAL-COMPACTED ONBOARD NETWORK Russian patent published in 2022 - IPC H04J14/02 

FIELD: data transmission.

SUBSTANCE: invention relates to onboard fibre-optic data transmission systems and can be used to form a fibre-optic system with a reconfiguration function on board of aerial vehicles, sea ships, space systems, and any ground technological facilities. The technical result is provided due to the fact that the spectral network multiplexer includes a matrix of interconnected optical adiabatic splitters, wherein a matrix of thermooptical switches is introduced into the optical demultiplexer, the OADM module of the control optical network circuit, and the optical data exchange circuit multiplexer, wherein a matrix of thermooptical switches is included in the optical transmitters of the transceiving optical module and the transmitting optical module as part of the circuits of the onboard optical network in order to implement the function of stable readjustment thereof to the required wavelength, wherein the amount of rows of said matrix is determined by the amount of wavelengths used in the circuits, and the amount of columns is determined by the amount of output ports included in the circuits.

EFFECT: expanded operating capabilities of the onboard fibre-optic data transmission system due to the provided function of flexible adjustment of the spectral component of the optical modules of the participants of data exchange in real time.
