Infoshare: European Time and Frequency Services – Principles, Challenges and Use Cases – 9 Mar 2021

9 March 2021, 13:00-15:50 CET

Time & Frequency (T&F) transport as an optical service has become a hot topic for the past ten years, mainly boosted by a dramatic improvement in performance. National Metrology Institutes (NMIs) in collaboration with NRENs have demonstrated three orders of magnitude higher stability of time and frequency services than any existing commercial service over distances of at least 1,500 km, offering tremendous potential for new services in a wide range of scientific, societal and economic domains.

The Technology Readiness Level (TRL) for such T&F services is in some cases now approaching 8 (complete and qualified) or 9 (proven in operational environment), while the growth of metrological links all around the world has motivated more and more optical equipment vendors to integrate T&F features into their product portfolios. However, there is no one-fits-all solution for how to deploy  T&F services. Rather, there are multiple T&F setups (unidirectional, bidirectional, quasi-bidirectional), parts of the spectrum (S-, C-, L-Band or in between), each dictated by the distinctive needs and requirements of the networks and the end-user applications.

Following on from our White Paper “Distributing New Performant Time and Frequency Services over NREN Networks“, this Infoshare will have an end-users oriented point of view and we will present the different services/methods currently available for implementation, review the situation in the European NRENs and present the current research and innovation projects (CLONETS-DS, TiFOON) working on the design of the future pan T/F European network. We want to show that implementing T/F services in an NREN environment is not only doable but safe and controlled.

This event will be followed by a second Infoshare dedicated to T&F services practical implementations and the challenges for European NRENs and the research community.
