Join NPL and BT to learn how time and synchronisation has developed over the past decades and about the fundamentals of traceable time and distribution.   Technical Focus Sessions will be presented on fixed and wireless infrastructure, monitoring, and GNSS derived time, to give you a solid foundation of how time is used and distributed… Read More


TiFOON partners PTB, LPL (Université Paris 13) and LNE-SYRTE have demonstrated more than 5 days of phase-coherent operation of the optical fibre link between Braunschweig and Strasbourg. The architecture, a combination of a Repeater Laser Station and Fibre Brillouin Amplifiers, was analysed over several long segments of continuous operation, covering 65 days of data in… Read More


TiFOON partners AGH and PSNC have studied the performance of optical frequency transfer in duplex unidirectional DWDM networks. This approach to optical frequency transfer uses existing telecommunication infrastructure without the need for modifications to the installed fibre and equipment, making it very cost effective compared to dark fibre or dark channel. The research, published in… Read More


The kick-off meeting for the three-year EMPIR project, Time and Frequency Over Optical Networks (TiFOON), was held at NPL from 24th – 25th June 2019. The consortium consists of 15 partners from 9 European countries (including the UK), ranging from NMIs through academic institutions to network operators and equipment manufacturers. It brings together long-established players… Read More


The EMPIR project TiFOON officially started on 1 June 2019. The kick-off meeting will be held on 24–25 June 2019 at the National Physical Laboratory.… Read More
