On differential group-delay statistics for polarization-modedispersion emulators
ABSTRACT We present a theoretical study on differential group-delay (DGD) statistics for common models of polarization-mode dispersion (PMD) emulators. Our study will show, for the first time to our knowledge, that the statistics for the length of the PMD vector will not necessarily behave as a system with three degrees of freedom when the number of sections in the PMD emulator is low. However, when the number of sections is large, i.e., 10 sections or more, the length of the PMD vector is well described with a system with three degrees of freedom

ABSTRACT: Polarization dispersion in single-mode fiber that contains arbitrary birefringence is described through a vector differential equation. Monte-Carlo simulations using this equation show good agreement with experimental measurements in a randomly birefringent fiber and with a previously reported analytic expression for the length dependence of the dispersion. We also correct an error made in earlier research and show that the probability density function for the magnitude of the dispersion at long lengths is Maxwellian rather than Gaussian as previously reported.Optics Letters 03/1991; 16(6):372-4. · 3.39 Impact Factor

ABSTRACT: Using various PMD statistics, and including higher-order terms, the performance of a PMD compensator with a fixed differential group delay (DGD) is evaluated. It is shown that the so-called Maxwellian case is the worst case both without and with compensation. Therefore, the optimization of a PMD compensator can be carried out with the Maxwellian case onlyOptical Fiber Communication Conference, 2000; 02/2000
