We propose an OSNR system margin estimation technique based on nonlinear noise insensitive OSNR monitoring. We experimentally demonstrate its accuracy less than 0.7dB estimation error for five-subcarrier DP-16QAM superchannel in dispersion-uncompensated transmission with various fiber launched power and various reaches.
