High first-order polarization mode dispersion (HiFO-PMD) sections are known to increase the overall first-order PMD (FO-PMD) of an optical
fibre link. Replacement of the HiFO-PMD regions with low-PMD fibres will drastically reduce the overall FOPMD of a fibre network link. In this paper, through simulation, we show that besides a HiFO-PMD section affecting the overall FO-PMD of a fibre link it also affects the overall second-order PMD (SO-PMD). The coupling angle between the other fibre sections making up a fibre link and the HiFO-PMD section determines whether first-order and second-order PMD can be introduced jointly or in isolation. Results show that propagating signals experience a high bit-error-rate (BER) when FO-PMD and SO-PMD coexist compared to when either of the two exist in isolation. However, SOPMD has more profound signal degrading effects compared to FO-PMD.
