TL;DR: Recently proposed DPC techniques for optical transponders are revised to generate high order high symbol rate modulation formats for next generation bandwidth variable transponder formats.

TL;DR: It is shown that the joint use of RF-pilot and back-propagation adds further improvement to OFDM performance when nonlinear compensation at the DSP receiver is employed.

TL;DR: In this article, the authors present system and detection conditions which lead to an improvement of the performance of coherent few-mode fiber transmission systems impaired by mode-dependent loss, where the detection conditions are described in terms of the detection parameters.

TL;DR: In this article, a dual parallel Mach-Zehnder-modulator (DPMZM) with first and second inner MZMs arranged parallel to each other is presented, and a calculation unit 52 is configured for receiving an in-phase component yI and a quadrature component yQ of a desired base-band signal.

TL;DR: In this paper, the authors compared the performance of different types of artificial neural networks (NNs) used for channel equalization in coherent optical communication systems and showed that the CNN+biLSTM is the best option when the computational complexity is not constrained, while when the complexity to lower levels, the three-layer perceptron provides the best performance.
