We present implementation of a pilot bidirectional line IPE-VUGKT for precise time transmission. Directional non-reciprocities are evaluated together with uncertainties. Emphasis is given to the evaluation of the Sagnac effect. Our approach improves significantly the uncertainty.
We propose and demonstrate a combination of two methods to stabilize end-to-end delay of an optical fiber link. Temperature conditioning method effectively compensates large slow delay changes while wavelength tuning compensates fast delay jitter. We present our measurement data for three basic telecommunication optical fibers. We summarize design rules for… (More)
