Impact of polarisation mode dispersion on 10 Gbit/s terrestrial systems over non-dispersion-shifted fibre

Depending on the launched state of polarisation, 10 Gbit/s system impairments are investigated experimentally in the presence of chromatic dispersion and variable differential group delay caused by polarisation mode dispersion. In addition, an actual fibre cable, not an optical simulator, was used to bring polarisation mode dispersion.
