TiFOON stands for “Time and Frequency over Optical Networks”.The EMPIR initiative is co-funded by the European Union’s Horizon 2020 research and innovation programme and the EMPIR participating states. To advance fibre-based frequency transfer capabilities in Europe towards a universal tool for time and frequency metrology and beyond.

Motivation

Redefinition of the SI second: Fibre links enable the remote clock comparisons required for the redefinition of the SI second, but their current reliability and availability are insufficient.

International time scales: Fibre-based time transfer offers performance and resilience beyond satellite techniques. Only combined optical frequency and time services in shared fibre will be economically sustainable.

Applications beyond metrology: Many applications in research and industry require synchronisation. Fibre links provide access to ultra-stable and accurate optical time and frequency references.
