Combination of Brillouin amplification and a repeater laser station supports frequency transfer with 20 digit accuracy

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
