| 概要 | Polarization Mode Dispersion (PMD) is the main limiting effect
of high bit rate transmission in long distance communication. It has
its origin in the randomly varying birefringence. A model, called the
Manakov PMD equation, has been introduced to study this phenomenon.
The particularity of this model is the various length scales appearing
in the equation. In this talk, I will explain how a limit theorem can
be proved (in the sense of convergence in law). I will give numerical
results on the limiting equation and estimations on the impact of the PMD. |
