摘要：

We have performed a time transfer over a distance of approximately 75 km using an asynchronous computer network based on optical fibers. In order to validate the results from this fiber-link, we have compared the results with a GPS-link, which consists of carrier phase observations. All electronic cabinets were equipped with temperature and humidity sensors. Here we present experiments where the temperature and humidity of the delay in the electrical components were investigated. All components showed some temperature dependence, but no significant humidity dependence was found. By using the derived temperature coefficient for the components the standard deviation of the difference between the fiber link and GPS link decreased from 243ps to 1.84ps.
