Abstract
An apparatus includes an optical transmitter and/or an optical receiver configured to use one or more artificial neural networks (ANNs) for geometric constellation shaping, the determination of constellation symbols to be transmitted, and/or the determination of the transmitted bit-word(s) or codewords. Each ANN has a plurality of bit-level processing portions connected to a symbol-level processing portion in a manner that enables bitwise processing of constellation-point labels.
