Bit error rate degradation related to differential group delay and input polarisation for 10-Gbit/s terrestrial systems in presence of chromatic dispersion and polarisation mode dispersion

摘要

10-Gbit/s system impairments are experimentally investigated in presenceof variable differential group delay caused by polarisation mode dispersion. The polarisation mode dispersion was brought by 68 km of standard fibre, including one cable specifically manufactured for this purpose.
