摘要

本文提出了光纤中PMD的近似估计，这是由于光纤电缆附近的雷击对地电磁场的影响而发生的。该估计是基于对具有偏心的光纤的PMD计算的类比。在雷击场的影响下，光纤中光的偏振面只要有很小的旋转，就会产生与主轴相同的正交模分布。当旋转小于20转时，可以用该方法进行估计。

Estimation of polarization mode dispersion (PMD) value in optical fibre during lightning strokes

The paper presents the approximate estimation of the PMD in an optical fibre, that occurs as a consequence of the electromagnetic field of a lightning stroke to earth in the vicinity of the fibre cable. The estimation is based on an analogy with the calculation of PMD in a fibre with eccentricity. A small rotation of the polarization plane of light in a fibre under the influence of a lightning field causes the same distribution of orthogonal modes to the main axis as a small eccentricity. Estimation can be made by this method if rotation is less than 20 grad.
