Equalization in Dispersion-Managed Systems Using Learned Digital Back-Propagation

Mohannad Abu-Romoh, Nelson Costa, Yves Jaouën +4

In this paper, we investigate the use of the learned digital back-propagation (LDBP) for equalizing dual-polarization fiber-optic transmission in dispersion-managed (DM) links. LDB…

Multi-Task Learning to Enhance Generalizability of Neural Network Equalizers in Coherent Optical Systems

Sasipim Srivallapanondh, Pedro J. Freire, Ashraful Alam +6

For the first time, multi-task learning is proposed to improve the flexibility of NN-based equalizers in coherent systems. A "single" NN-based equalizer improves Q-factor by up to…

Knowledge Distillation Applied to Optical Channel Equalization: Solving the Parallelization Problem of Recurrent Connection

Sasipim Srivallapanondh, Pedro J. Freire, Bernhard Spinnler +4

To circumvent the non-parallelizability of recurrent neural network-based equalizers, we propose knowledge distillation to recast the RNN into a parallelizable feedforward structur…

Low Complexity Convolutional Neural Networks for Equalization in Optical Fiber Transmission

Mohannad Abu-romoh, Nelson Costa, Antonio Napoli +3

A convolutional neural network is proposed to mitigate fiber transmission effects, achieving a five-fold reduction in trainable parameters compared to alternative equalizers, and 3…
