Wavelength division multiplexed fiber optic link for RF polarization diversity receiver

摘要: A single transmission optical fiber is used to transmit RF signals of the same frequency but different polarization from a source diversity receiver without introducing interference between signals. The incoming signal one modulates first laser transmitter operating at wavelength, and other second different, wavelength. two modulated beams are combined in an coupler whose output connected leading receiver. At receiver, wavelength division multiplexing separate out carriers. modulate transmitters separately recovered via photodiode detectors provide inputs
