The annual global Internet traffic will 127-fold increase from 2005 to 2021, with a Compound Annual Growth Rate of 24% from 2016 – 2021. In the context of such extraordinary traffic growth, the Consortium of 14 academic and industrial highly qualified institutions created the Wideband Optical Networks (WON) European Training Network (ETN), to promote international, inter-sectorial and multi/inter-disciplinary research activities and career development for a generation of early stage researchers.
Solutions identified within WON will enable to overcome a possible traffic-crunch by achieving a 10-fold increase in the usable optical bandwidth of single-mode fibres.
WON is covering all topics and expertise from design and development of photonic components, novel digital signal processing algorithms and system modelling to network management and control.
The digital signal processing group is investigating efficient transmitter impairment estimation and compensation schemes enabling wideband operation as well as advanced coherent transponder monitoring capabilities for wideband systems.
