SENSEI: Unlocking infrastructure and environmental sensing capabilities of telecommunication fibre networks
SENSEI aims to develop new photonic devices and technologies to enhance the security, resilience, and efficiency of telecommunication fibre networks through improved supervision capabilities, while exploiting them as large-scale distributed environmental sensors. Funded by the European Commission under the Horizon Europe programme with €5 million over 3 years, the project brings together 15 partners from […]
The REFIMEVE national research infrastructure enables the distribution of ultra-stable frequency and time signals across 9,000 km of optical fiber, connecting over 30 laboratories throughout France. The exceptional accuracy of these signals—reaching beyond 10-18 — supports a wide range of scientific applications in fundamental physics, quantum technologies, photonics, geodesy and climate research, and the synchronization of large instruments in astrophysics and particle accelerators.
