NPL, PTB and LNE-SYRTE to Carry Out International Clock Comparisons via Optical Fibre

The National Physical Laboratory (NPL) is working with Physikalisch-Technische Bundesnastalt (PTB) and Observatoire de Paris (LNE-SYRTE) to carry out International Clock Comparisons via Optical Fibre (ICOF).

ICOF, a GÉANT Open Call project, aims to enable a state-of-the-art atomic clock comparison, using the GÉANT long haul dark fibre link between NPL, London, and OBSPARIS, Paris.

The results of the ICOF project, in combination with those of the Joint Research Project NEAT-FT of the European Metrology Research Programme (EMRP), will pave the way for improved clock comparisons within Europe and the dissemination of highly accurate and stable frequency and timing signals to academia and industry.
