RADIO-PHOTON FIBRE-OPTICAL COMMUNICATION SYSTEM (EMBODIMENTS) Russian patent published in 2023 - IPC H04B7/00 

FIELD: optical communication; information transmission technology.

SUBSTANCE: invention can be used to create a new generation of fibre-optic communication systems. The technical result is achieved due to the fact that the radio-photonic fibre-optic communication system, which includes a series-connected optical transmitter, an electro-optical modulator, an optoelectronic receiver, an analog-to-digital converter and a digital demodulator, has optical splitters, (n-1) electro-optical modulators and electronic adder introduced, a broadband laser emitting at n wavelengths is used as an optical transmitter, the outputs of which are connected to the inputs of n electro-optical modulators using a fibre optic cable containing n optical fibres, according to the number n wavelengths of the broadband laser radiation, the optoelectronic receiver is made in form of a matrix with n sensitive elements, n outputs of electro-optical modulators are optically coupled with the help of a fibre-optic cable to n sensitive elements of an optoelectronic receiver, the outputs of which are connected to the multi-channel input of the adder, the output of which is connected to the input of an analog-to-digital converter connected to a digital demodulator, n optical carriers from the output of a broadband laser are supplied to the optical inputs electro-optical modulators, and the same information radio signal or n different information signals are fed in parallel to their n modulating inputs.

EFFECT: increase of noise immunity of a radio-photon fibre-optic communication system, increase of the volume of transmitted information signals and reduction of weight and size dimensions of the system’s transmitting part.
