Abstract

We demonstrate the transfer of an ultra stable microwave frequency by transmitting a 30 nm-wide optical frequency comb over 86 km of installed optical fiber. The pulse train is returned to the transmitter via the same fiber for compensation of environmentally-induced optical path length changes. The fractional transfer stability measured at the remote end reaches 4 × 10-17 after 1600 s, corresponding to a timing jitter of 64 fs.
