In this paper, a technique for compensating for the polarisation mode dispersion of a 10 Gbit/s non-return to zero (NRZ) installed fiber link (45 km, 80 ps mean differential group delay), using a variable polarisation delay line and a set of polarisation controllers is presented.Abstract:
A technique for compensating for the polarisation mode dispersion of a 10 Gbit/s non-return to zero (NRZ) installed fibre link (45 km, 80 ps mean differential group delay), using a variable polarisation delay line and a set of polarisation controllers is presented. The variation of the output polarisation with frequency over the signal bandwidth was monitored using a frequency-resolving Stokes-polarimeter. A control loop is used to minimise the RMS deviation of the polarisation state at the receiver.read more

TL;DR: In this paper, the authors demonstrate that polarization scrambling combined with degree of polarization evaluation enables polarization mode dispersion (PMD) compensation without feedback fading due to varying input polarization, and demonstrate that PMD of an installed fiber as well as PMD in an emulator can be successfully compensated.

PMD in high-bit-rate transmission and means for its mitigation
TL;DR: Recent progress in PMD mitigation and compensation is reviewed, including their use in a 40-Gbit/s carrier-suppressed return-to-zero differential phase-shift keying experiment, and progress in using LiNbO/sub 3/ devices is reported on.

Analysis of PMD compensators with fixed DGD using importance sampling
TL;DR: In this article, the authors use importance sampling to analyze polarization-mode dispersion compensators with a constant differential group delay (DGD) element and show that the optimum value of the fixed DGD element of the compensator can reduce the outage probability by several orders of magnitude, even though it does not provide a substantial reduction of the average penalty due to polarization mode dispersion.
