Optical Networks & Systems

The goal of the ONS department is to contribute in defining the evolution of future transport networks (spanning from metro packet/circuit aggregation to core optical networks) towards intelligent (dynamic, self-star), high-capacity, low-cost, highly-flexible, scalable, and energy-efficient software-defined optical networks seamlessly integrated with massive cloud/fog computing and storage services.

To achieve this goal, it focuses on two main research lines:

  1. Network Control and Service Management, to perform research on SDN control architectures, protocols and traffic engineering algorithms for autonomic and  disaggregated optical and packet transport networks, and well as on service orchestration architectures for end-to-end NFV network services and network slicing, integrating transport networks with edge computing and cloud.
  2. Optical Transmission and Subsystems, to perform research on programmable multidimensional WDM/SDM optical transmission systems, advanced photonic transceivers, impairment mitigation and AI-assisted performance monitoring techniques, as well as flexible/agile and advanced/efficient technologies and subsystems for software-defined high-capacity optical networks.

Demonstration and validation of proof of concepts are performed by means of the ADRENALINE Testbed®, an experimental infrastructure designed and developed by the CTTC ONS Department to conduct cutting-edge research activities.
