A lightweight optical constellations modeling method based on concatenating ANNs is
proposed. Statistical validation of the reproduced constellations is shown. The method …

The impact of the wavelength selective switch (WSS) filtering penalty on the signal integrity
of elastic wavelength division multiplexing (WDM) network becomes increasingly important …

A novel WSS-free ROADM based on optical splitter/coupler and coherent detection is
experimentally demonstrated, cost-effectively achieving similar functions and performances …

(English) Optical communications have been extensively investigated and enhanced in the
