DUAL-CIRCUIT REAL-TIME INFORMATION TRANSMISSION SYSTEM BASED ON AN ALL-OPTICAL WAVELENGTH-DENSE ON-BOARD NETWORK Russian patent published in 2021 - IPC H04L12/853 

FIELD: information transmission.

SUBSTANCE: for the achievement of result, a two-circuit real-time information transmission system based on an all-optical wavelength-dense onboard real-time network contains at least two computing modules in which software applications operate, an optical communication line, an optical multiplexer and an optical demultiplexer, a spectral network terminal containing a transmitting and receiving optical modules, and differs in that the spectral network terminal additionally includes a transmitting and receiving optical module, which contains an optical transmitter, an optical splitter, an optical demultiplexer, an OADM module, optical receivers of general information of computing modules, optical receivers of the computing module information and a transceiver controller, in which the output memory area is organized in the form of a ring buffer, while the transceiver controller is connected to the optical receivers of the general information of the computing modules, which are connected with an optical splitter through the optical demultiplexer of the transceiver module, and the transceiver controller is connected to the OADM module through the optical receivers of the computational module's own information and the optical transmitters of the transceiver module.

EFFECT: technical result consists in increasing the reliability of information exchange between onboard systems in real time with guaranteed message delivery.
