Abstract [en]

The two color one-way frequency transfer in optical fiber is an alternative method to two-way time and frequency transfer that is useful if there are unknown asymmetries in the connection. The method is possible to use in existing infrastructure and is able to coexist with data channels for example in WDM systems, which make it possible to broadcast to multiple users and enables the user to be anonymous to the time or frequency transfer. The goal is to develop a stable one-way transfer method comparable with well-established two-way methods, with a precision and accuracy comparable to readily used satellite-based methods. The recent progress in the determination of the error sources introduced by the equipment used for phase comparisons as well as results from increasing the modulation frequency is presented. It is shown how the increase in frequency also enhances the precision, and a result from real time phase stabilization is presented. Furthermore, results from the introduction of a third wavelength are presented, with experimental data over one week periods.
