Longitudinal gOSNR Monitoring by Receiver-side Digital Signal Processing in Multi-Span Optical Transmission System

10 Oct 2023  ·  Choloong Hahn, Junho Chang, Zhiping Jiang ·

We propose the world first longitudinal gOSNR estimation by using correlation template method at Rx, without any monitoring devices located in the middle of the link. The proposed method is experimentally demonstrated in a 12-span link with commercial transceiver.
