Determining the Rate of PMD Compensation in Deployed Aerial Optical Fibres Through SOP Monitoring

In this paper, statistical distributions for First Order Polarization Mode Dispersion (FO-PMD) and Second Order Polarization Mode Dispersion (SO-PMD) are experimentally confirmed when measured using the FTB-5700 Single-Ended Dispersion Analyzer instrument for aerial optical fibres. The authors also determined the time scale over which to compensate FO-PMD in aerial fibres using the directional time drift auto-correlation function method. It is slightly higher than 390s for SOP measurements made on a particular windy and hot day. This is due to the fact that the changes of the PMD vector are known to be slower than the State Of Polarization (SOP) changes.
