Measuring Optical Signal-to-Noise-Ratio (OSNR) in live Dense Wavelength Division Multiplexing (DWDM) systems using polarization multiplexed transmission (Pol-Mux) is an unsolved challenge. In this paper a novel method to calculate OSNR from the correlation between spectral components in the optical spectrum of a transmission signal is proposed. Attend Viavi’s #OFC poster session with Wolfgan Moench on OSNR in Coherent Systems on 3/23.
