Fourier Transform Spectral Analysis Based Fiber Nonlinearity-Insensitive OSNR Monitor (JW1A.117)

Presenter: Zhuili Huang, Chongqing University

A fiber nonlinearity-insensitive OSNR monitoring technique was developed based on Fourier transform spectral analysis and shallow neural networks for function fitting. The results show monitoring errors are less than ±0.5dB for 3-channel 25GBaud PDM-QPSK signals.
