    "abstract": "We use a new technique to disseminate microwave reference signals along\nordinary optical fiber. The fractional frequency resolution of a link of 86 km\nin length is 10-17 for a one day integration time, a resolution higher than the\nstability of the best microwave or optical clocks. We use the link to compare\nthe microwave reference and a CO2/OsO4 frequency standard that stabilizes a\nfemtosecond laser frequency comb. This demonstrates a resolution of 3.10-14 at\n1 s. An upper value of the instability introduced by the femtosecond\nlaser-based synthesizer is estimated as 1.10-14 at 1 s.",
