An In Band OSNR Monitoring Technique Based on Normalized Autocorrelation Function
We experimentally demonstrate a novel in band OSNR monitor based on normalized autocorrelation function, which is insensitive to both CD and input optical power. OSNR up to 26 dB is successfully monitored for 112 Gbit/s PDM QPSK.
