Convolutional Neural Network based Nonlinear Classifier for 112-Gbps High Speed Optical Link

Abstract

We have designed a novel convolutional neural network based nonlinear classifier that outperforms traditional Volterra nonlinear equalizers. A BER of 3.50 x 10(-6) is obtained for a 112-Gbps PAM4 EML-based optical link over 40-km SMF transmission.
