Decrease of the Link PMD by Fiber Exchange and Investigation of the PMD Distribution along Buried Optical Fibers with a POTDR

I. INTRODUCTION The fiber network of most network operators generally comprises a heterogeneous mixture of fibers and cables, produced by different vendors over many different years. Thus, there can be a correspondingly important variation in the physical properties of deployed fibers. Along with fiber attenuation and chromatic dispersion, polarization mode dispersion (PMD) is an important […]
