Reducing the time transfer uncertainty in the fiber optic time and frequency dissemination system

In this work we present a newly designed compensating module, which reduces the delay mismatch between two integrated delay lines used in time transfer system. In this work we show the measured results of the compensation efficiency, both in nominal temperature, and for ± 5°C temperature excursions. We find the remaining mismatch as no greater than 3 ps. After applying the compensation module, the problem of the delay lines mismatch go below other factors limiting the overall system performance.
