Claim 3:
4. The photonic frequency converter according to claim 1, wherein in the optoelectronic oscillator (OEO) where the frequency signal f0 is generated, the signal with the frequency f1 and the signal with the frequency f2 undergoes intermodulation in the MZ electro-optical modulator with the frequency signal f0 generated in the optoelectronic oscillator (OEO), an intermodulation signal, with frequencies above and below the frequencies f1 and f2 (f0−f1, f0−f2, f0+f1, f1−f2, etc.), is selected by at least one selection filter after the power splitter and a second amplifier connected after the single photodetector of the optoelectronic oscillator (OEO), and after the second amplifier there are the selection filters of frequency above and below the frequencies f1 and f2, and signals after the selection filters following the second amplifier represent output signals with frequencies above and below the frequencies f1 and f2, that can be used in transmission (T) and reception (R) steps.
