“…To present this large amount of data, we partioned the time series into bins of 1 ms and calculated the largest SOP change by calculating the angle on the Poincare sphere for the most separated two points in each bin. We then formed histograms plotting number of ocurences for each maximum excursion [3]. Figure 3 shows the histogram from the 110 km fiber link measurement.…”

Two high-PMD long distance routes were characterized and used to test an optical polarization mode dispersion compensator (PMDC) under field conditions. For this trial, 110 km routes with mean PMD values of 25 and 26.5 ps were provisioned with commercial WDM transport equipment and tested for several weeks. The route was comprised of three spans of characterized fiber that followed railroad tracks. We show the temporal variation of the output polarization state and the evolution of first-and second-order PMD spectra over 7 days. The deployment of a variablelength PMDC on these links allowed error-free transmission of an OC-192 signal. Splitting the output to receivers with and without PMDC demonstrated specific PMD events that caused errors in the absence of a PMDC.

“…One must remember that complete coverage of the Poincaré sphere does not mean that every (or even most) DGD transitions have occurred. The dynamic behavior is controlled by the time evolution step ( ) and the pdf width ( [7]). …”

“…The emulator was set to a fixed value and update rate was set to 10 and 20 ms, respectively. The SOP data was sampled at the same rate and an arc-length calculation was performed (see [7] for details). The model was made up of the same number of PMF sections and polarization controllers as the DPMDE.…”

“…The emulator we present [6] takes this one step further, from others' work, by randomly varying the birefringence of each fiber squeezer in a biased manner to track the dynamics of PMD in time and allows for different cable types to be emulated. A probability density function (pdf), similar to the one presented in [7], is used to create the biased changes. A fiber squeezer model is derived to accurately model the birefringence changes of the emulator.…”

Abstract-A polarization mode dispersion (PMD) emulator is presented which accurately follows the dynamics of PMD in field optical fiber. A modification on a dynamic mode coupling waveplate model is presented to model the emulator. It is found that the emulator and model can accurately describe the dynamical behavior of the state of polarization and thus PMD in a field fiber. The emulator is shown to be repeatable. Generally, the dynamical PMD emulator is shown to cause more realistic bit-error-rate degradation than a classical PMD emulator.Index Terms-Optical communication, optical fiber measurements, optical fiber polarization, optical fiber theory.
