✦ Synopsis
The relative optical frequency stabilities of three optical reference units at 1547.825 nm were examined. The reference units were located at different places in Berlin and connected via several kilometeres of optical fiber. The three optical signals were heterodyned to measure the frequency stabilities, which were better than 2 × 10 -11 at 1000 s sample time.
