Time-frequency transfer and time calibration dataset of 515km field fiber links

The dataset was collected from June 20, 2023 to July 20, 2023 in Beijing Niutuo and other places, and the link delay was measured by the time interval measuring instrument SR620, and the frequency deviation data and phase noise data were collected by the phase noise analyzer 5125A. The link delay data is plotted by origin, and the phase noise data is also plotted by origin. The frequency deviation data is calculated by using the MATLAB self-built algorithm to calculate the frequency stability ADEV and the time stability TDEV.
