 Project objective

The delivery of fast Internet connections all over Europe is a primary goal of Horizon 2020. In order to avoid the upcoming capacity crunch on transport optical networks, there is an urgent need for a strong investment in the research and development of future-proof optical broadband infrastructures. The Flex-ON project will investigate new technological paradigms in terms of signal generation, digital processing and control-plane management for novel flexible and high-capacity transport optical networks. The primary technical objective of the project is to develop and implement a flexible transceiver prototype with intelligent reconfigurability and arbitrarily low bit-rate granularity. The development of this technology will enable to increase the network capacity and the spectral/energy efficiency, while providing a future-proof flexible solution for an increasingly heterogeneous global network.

The main scientific/industrial contributions of the project include: - the optimization of signal modulation to improve spectral efficiency and bit-rate granularity; - the development of novel DSP strategies and algorithms to enable flexible networking; - the development of novel numerical tools for physical layer modelling under the nonlinear (NL) propagation regime; - the optimization of NL compensation methods to improve the trade-off between spectral efficiency and signal reach.

In order to guarantee a sustainable and smooth upgrade of currently installed optical transmission systems, Flex-ON encompasses a dual-generation approach: - 1st generation: fixed frequency grid (ITU-T: 50 GHz) and fixed symbol-rate transceivers with variable bit-rate enabled by time domain hybrid QAM techniques; - 2nd generation: flexible frequency grid (ITU-T G.694.1: 12.5 GHz) and variable symbol-rate transceivers.

The tight collaboration with industry players ensures that the newly proposed concepts, software and prototypes will enhance the European competitiveness in the telecom sector.
