Preparing the Advancement of the state of the art of submarine cable infrastructures (CSA)

Summary

Submarine connectivity infrastructures are vital for Europe’s strategic autonomy and economic security, with potential secondary uses such as early-warning systems against natural hazards. To stay at the technological forefront, Europe must advance not only cable technology but also related components like repeaters, landing stations, control centres, acoustic sensor networks, and cybersecurity. While some progress comes from broader research in optical communications and network management, there is a need for a dedicated roadmap and SRIA focused on submarine cable technologies. Key research areas may include multi-core fibre, digital signal processing, repeater systems, intelligent and acoustic sensing, oceanographic sensors, cable network management, underwater robotics, and wireless sensor networks for monitoring and threat detection.

Detailed Call Description

  • Enabling technologies applicable to submarine connectivity infrastructures and systems, including its secondary use for pre-warning systems against natural hazards, are increasingly important to ensure Europe’s strategic autonomy as well as economic security. Achieving such goals requires that Europe remains at the technological edge not only with regards to the cable technology itself but also all the other critical elements composing the submarine cable infrastructure such as repeaters, landings stations, operational control centres, underwater acoustic sensor networks (UASN) or cable communications cybersecurity.
  • While some of the necessary research is indirectly conducted through mainstream research activities in generic technologies (e.g., optical communications or network management software), more specific research is needed to address the particular needs and advancement of submarine cable infrastructures and systems. However, the specific research needs still need to be identified, which supports the need to develop a specific roadmap and SRIA for research and innovation in submarine cable technologies. Such research efforts may address some of the following (non-exhaustive) domains: Multi-core fibre (MCF) technology, Digital Signal Processing, repeater systems, intelligent sensing, advanced Digital Acoustic Sensing (DAS), strain and temperature sensing, oceanographic sensors for continuous, real-time trans-oceanic measurements (monitor water body), logical layer and cable network management systems, underwater robotics to improve the construction, maintenance and repair of submarine cable infrastructures, and other innovations, such as wireless sensor networks (WSN) to monitor permanently submarine cable infrastructure and to detect possible threats.

Projects are expected to develop synergies and ensure complementarities with projects under CEF Digital, the Digital Europe Programme (DEP) and the Smart Networks and Services (SNS) Joint Undertaking.
