5. A related technique measures and stabilizes the phase of an rf modulation carried by the fiber as an AM signal. This system permits precise time and rf frequency transfer via fiber. See T. P.

8. -5 rad/√Hz at −10 kHz, reducing at higher frequencies as a result of reduced phase noise from the fiber, and reducing also toward low frequencies because of the higher gain of the second-order phase-lock loop.
9. For the best resolution it is necessary to run both rf synthesizers from the same reference for these tests, but we emphasize that, in practice, only a single crystal oscillator is needed for the AOM1 source.
10. Approximately 0.2-μbar/√Hz of pressure below 300 Hz was produced by a small heat gun (turned on cold) located 50 cm from the fiber and blowing away from it.
