We propose a novel in-band optical signal-to-noise ratio(OSNR) monitoring method based on polarization interference.The method realizes a monitoring accuracy of±0.5 dB within the range of 9-34 dB.Our results indicate that the proposed method is transparent to bitrate and modulation format,as well as independent of polarization mode dispersion and chromatic dispersion.
