In this paper, the authors measured the time evolution of polarization mode dispersion (PMD) for installed aerial and buried cables and for a spooled fiber in a temperature controlled chamber.Abstract:
The fluctuation of polarization mode dispersion (PMD) due to environmental change is an important issue for fiber-optic communication systems. We measure the time evolution of PMD for installed aerial and buried cables and for a spooled fiber in a temperature controlled chamber. The results show that PMD fluctuates much more rapidly for aerial cables than for buried cables. The magnitude of PMD is different for the three fibers and our results also show that the magnitude of PMD fluctuation depends on the magnitude of the PMD.read more

Polarization-Mode Dispersion
TL;DR: In this article, it is shown that fluctuations in the polarization mode and fiber birefringence produced by the environment lead to dispersion that varies statistically with time and frequency.

Long-term measurement of PMD and polarization drift in installed fibers
TL;DR: In this article, the authors reported the most detailed long-term measurement of polarization mode dispersion (PMD) made to date, and quantified the temporal drift by computing the autocorrelation function of the PMD-vector analytically, both with respect to wavelength and to drift time.

Polarization Mode Dispersion of Installed Fibers
TL;DR: The authors discuss the proposition that most of the temporal PMD changes that are observed in installed routes arise primarily from a relatively small number of "hot spots" along the route that are exposed to the ambient environment, whereas the buried shielded sections remain largely stable for month-long time periods.

Origins and control of polarization effects in single-mode fibers
TL;DR: In this article, the basic birefringences that couple the two modes and change the polarization state along the fiber are reviewed, and three cases of uniform, phase-matched, and random coupling are considered.

How accurately can one measure a statistical quantity like polarization-mode dispersion?
TL;DR: In this paper, the authors present analytical formulae and numerical data characterizing the intrinsic limitation common to all measurement techniques, namely that all measurements of polarization-mode dispersion involve thus an averaging over a finite sample set.
