|EO-Net will carry out cutting-edge research with the aim to design and demonstrate a novel networking concept based on “elasticity” for improved utilization of resources in Wavelength Division Multiplexed (WDM) optical networks. By “elasticity” it is meant that a certain number of transmission parameters such as the optical data-rate, the modulation format or the wavelength-spacing between channels, which are fixed in currently deployed networks, will be made tunable.
Elasticity will thus allow improved matching between the transmission parameters, the network infrastructures (and the physical impairments they cause to optical signals) and the traffic profile. The benefits will be wide-ranging, including in particular increased available network capacity, lower cost per bit, better energy efficiency and better scalability.
EO-Net will provide a global picture of elastic optical networks by integrating research activities focusing on all the aspects of networking that are impacted by an elastic optical layer, namely:
The outcomes of the aforementioned research activities will be integrated into a multi-layer demonstrator to validate the concept of network elasticity and will also be the basis for detailed techno-economic studies assessing the cost of the proposed solution and assessing which level of elasticity is most appropriate for future competitive products. Elastic functionalities are in particular expected to be transferred on a short time scale to 100Gb/s coherent technologies currently under development.
