Abstract

High-resolution time and frequency transfer between remote locations are of major interest for many applications, such as tests of general relativity and temporal variation of fundamental constants, future redefinition of the second, relativistic geodesy, and navigation. As a very promising alternative, optical fiber links are intensively studied for a decade by several groups, for frequency transfer. They demonstrate impressive results far beyond the GPS capabilities on distances up to 2000 km thanks to an active compensation of the fiber propagation noise [1-2].
