Experimental Demonstration of a Novel Fourier Convolution-based Network Equalizer for 112 Gb/s Upstream Passive Optical Networks

A novel Fourier Convolution-based Network (FConvNet) equalizer is experimentally demonstrated to enhance the receiver sensitivity by 2 dB and 1 dB compared to a 51-tap Sato equalizer and benchmark machine learning algorithms, respectively, for a 112 Gb/s upstream passive optical network.
