Brillouin amplification supports accuracy in optical frequency transfer over 1400~km of underground fibre
Sebastian M. F. Raupach, Andreas Koczwara, Gesine Grosche
We investigate optical frequency transfer over a 1400~km loop of underground fibre connecting Braunschweig and Strasbourg. Largely autonomous fibre Brillouin amplifiers (FBA) are t…

Optical frequency transfer via a 660 km underground fiber link using a remote Brillouin amplifier
S. M. F. Raupach, A. Koczwara, G. Grosche
In long-haul optical continuous-wave frequency transfer via fiber, remote bidirectional Er-doped fiber amplifiers are commonly used to mitigate signal attenuation. We demonstra…
