June 29, 2021 The EMPIR TiFOON (Time and Frequency Over Optical Networks) project held a highly successful stakeholder workshop on 9-10 February 2021. More than 100 participants from a broad range of backgrounds heard an informative series of presentations from experts in industry, academia and research. A discussion session at the end of each day collected feedback and ideas from the participants, addressing 4 questions: What applications are likely to benefit from high-performance T&F dissemination over fibre links, and when will they need it? What dissemination methods and network types would be most suitable to meet the needs of these applications? What steps are needed to enable high-performance fibre T&F dissemination methods to be set up and operated? What should the TiFOON project do to support this process? The ideas collected during those discussions have been summarised in a document that can be downloaded here (also available through Publications).
