We numerically demonstrate an all-optical nonlinearity pre-compensation module for state-of-the-art long-reach Raman-amplified unrepeatered links. The compensator design is optimized in terms of propagation symmetry to maximize the performance gains

In this paper, we propose an in-service method to simultaneously monitor both nominal and effective values of differential group delay (DGD) in wavelength-division multiplexing (WDM) optical communication systems, in a per channel basis. The method i

The CMA in 112 Gb/s PM-QPSK coherent receivers has a relatively slow convergence speed. This paper proposes and experimentally demonstrates a simple gain adaptation method that improves the convergence of a receiver dynamic equalizer.
