Environmental conditions affect the birefringence of an optical fibre which in turn leads to fluctuations in its Polarization mode dispersion (PMD). Fluctuations in PMD make compensation for it in optical fibres very complicated. In this paper, fluctuations of first-order polarization mode dispersion (FO-PMD), FO-PMD coefficients and second-order polarization mode dispersion (SO-PMD) are monitored over time and also with respect to the environmental conditions. Long term measurements of FO-PMD have been done before by Mudau (2008) using the Generalized Interferometry Technique (GINTY) only. However, in this current study the FO-PMD coefficients and SO-PMD fluctuations were also monitored in addition to making a comparison between the measurements obtained using the Single-ended Dispersion Analyzer (FTB-5700) and the GINTY. These measurements were made on a 14.8 km long deployed aerial optical fibre that links St. Albans to Rockland transmission stations in Port Elizabeth, South Africa. The weather information was obtained from the Kestrel 4500 pocket weather tracker that was set up at St. Albans transmission station. So, for good PMD compensation, PMD should be monitored for a very long period of time or use an instrument that can accurately measure it even when the optical fibre is exposed to harsh environmental conditions.

“…Low SOP spread due to the presence of the HiDGD section means all the wavelengths have almost similar polarization states thus making it difficult to subdivide a fibre into different communication channels for WDM or DWDM to address the demand in bandwidth. Ireeta et al [13] pointed out that the SOP spread can be used to help determine the rate at which accurate PMD compensation can be done in optical communication systems. .…”

Research to date has shown that high differential group delay (HiDGD) sections along an optical fiber network link are the major contributors to PMD. PMD has deleterious effects on propagating optical signals. In this paper, we show the effect a HiDGD section has on the output state of polarization (SOP) of propagating light. Experimental results in this paper show a reduction in the range of the output SOP spread with an increase in the DGD of the HiDGD section to a given asymptote (a minimum) i.e. when HiDGD ≥ 35ps. However, the output SOP spread and its asymptote solely depends on the location of the HiDGD section along the fiber link length. A small output SOP spread over the entire wavelength scan covers a few polarization states on the Poincaré sphere and vice versa for a large output SOP spread. The small output SOP spread over the entire wavelength range (50 nm in steps of 0.3 nm for this study) is an indicator that the polarization capabilities of optical telecommunication signals are restricted to minute SOPs.
