We propose a novel optical signal-to-noise ratio (OSNR) monitoring scheme using a Sagnac interferometer based on fiber birefringence. The proposed OSNR monitoring scheme is demonstrated in single and dual polarization systems, which shows incident polarization independence and dispersion insensitivity.
