Abstract :
We will discuss our work on a one-way optical fiber frequency transfer system. The link removes thermally generated delays through sensing the difference in temperature dependent changes in the group index of the fiber for two wavelengths. The system monitors the phase difference between two amplitude-modulated lasers at the edges of the C-band. Using this signal, a temperature controlled spool of fiber compensates for thermally induced phase excursions in the link. We will present preliminary results as well as a discussion of performance limitations.
