Popis: Results of optical frequency transfer over a carrier-grade dense-wavelength-division-multiplexing(DWDM) optical fiber network are presented. The relation between soil temperature changes on a buriedoptical fiber and frequency changes of an optical carrier through the fiber is modeled. Soil temperatures,measured at various depths by the Royal Netherlands Meteorology Institute (KNMI) are compared withobserved frequency variations through this model. A comparison of a nine-day record of optical frequencymeasurements through the 2 × 298 km fiber link with soil temperature data shows qualitativeagreement. A soil temperature model is used to predict the link stability over longer periods(days–months–years). We show that optical frequency dissemination is sufficiently stable to distributeand compare, e.g., rubidium frequency standards over standard DWDM optical fiber networks usingunidirectional fibers.
