Phase noise spectra of the microwave spin-wave photonic generator were measured for various lengths of the optical fibres. Results show that the increase in fibre length from 200 m to 4 km reduces the phase noise tending to a limit value around -146.5 dBc/Hz at a 10-kHz offset from a generation frequency of 10 GHz.
