Interferometry for polarization mode dispersion measurements in single fibres

We present two interferometric techniques for the measurements of the polarization mode dispersion of standard (i.e. circular) single-mode fibers. The first method uses an interferometric loop and works in the frequency domain. The second uses a polarization maintaining Michelson interferometer and works in the time domain. Their output are related by a Fourier transformation. Both techniques provide information about the entire statistical distribution of the polarization mode delays. Also, both techniques can be applied to the characterization of installed lines. The setups are presented, the principle of the measurements are discussed and examples of results are shown.
