Comparison of Polarization Fading Compensation Methods for Broadband Microwave Photonic Links by Introduced Noise and Achievable Dynamic Range

Two methods for compensation of polarization fading in microwave photonic links have been studied. Comparison of noise characteristics has been performed and factors limiting the dynamic range of microwave photonic link have been analyzed on an example of a link with an external remote electrooptic...

Description
Summary:Two methods for compensation of polarization fading in microwave photonic links have been studied. Comparison of noise characteristics has been performed and factors limiting the dynamic range of microwave photonic link have been analyzed on an example of a link with an external remote electrooptic modulator. The possibility of reaching spurious-free dynamic range close to the shot-noise limit SFDR 3 ≈ 116 dB Hz –2/3 has been demonstrated for 1000 m microwave photonic link.
