Abstract : The unique property of the ultra low losses of optical fiber can be used in the field of metrology to reach large delays, which are equivalent to ultra high quality factors. It is thus possible to realize, with a fiber spool, passive frequency references which can be used to characterize frequency sources of different type : microwave frequency sources and optical frequency sources. This paper describes two different benches, one in the microwave domain and the other one in the optical domain, which are based on optical fiber delay lines. The first bench is used to measure the phase noise of very high spectral purity microwave sources. The other one is dedicated to the measurement of the frequency fluctuations of ultra high spectral purity infrared lasers.
