HENIAC project adresses challenges related to the physical layer of tomorrow's Internet. Driven by video, including emerging 3D applications, and exploding mobile data trafic fueled by the democratisation of smartphones, the global telecommunication network is experiencing major technological challenges. After the recent introduction of 100 Gb/s optical communication systems, next generations providing 400-Gb/s and 1-Tb/s capacities are already asked for by companies like Facebook and Google, or operators like Verizon.

HENIAC project aims at developping new very high speed digital-to-analog converters to enable next generation optical communication systems based on multilevel optical modulation formats, allowing to reach 400 Gb/s per modulated wavelengths, and paving the way to future 1-Tb/s systems.

HENIAC project will provide innovations in 6 key areas:

  • Very high speed digital-to-analog converters.

  • Extensive electro-magnetic simulations will allow to specify and optimise all critical RF interfaces, especially the one between the DAC and the electro-optical modulator.

  • Packaging technologies will be developped in order to provide devices which are compatible with Surface-Mountable-Technology.

  • System implementation will be done through ad-hoc FPGA-based evaluation boards in order to provide flexible and optimised sub-systems.

  • Advanced digital signal processing for optical communications will be implemented to provide demodulation and error correction algorithms in order to improve the system's performance when using complex modulation formats like PDM 16QAM and PDM 64QAM.

  • Multilevel optical modulation formats, such as PDM 16/64QAM, will be investigated through system experiments in back-to-back and transmission configurations. Their properties with respect to OSNR requirements and transmission distance will be assessed. During these system experiments, 400 Gb/s will be achieved and 1 Tb/s will be demonstrated through a dual-carrier technique.
