Polarisation Mode Dispersion: worst case modeling and impact on high-data-rate transmission in the optical network of Deutsche Telekom

摘要

The regenerator-free transmission distance of ultra-long-haul, dispersion-managed, optical WDM-transmission-links is ultimately determined by accumulating ASE-Noise of optical amplifiers and Polarisation-Mode-Dispersion (PMD) of the fiber-material. Therefore the applicability of the fiber-infrastructure of Deutsche Telekom to transport optical channels at 10 Gbit/s and 40 Gbit/s over sufficiently long distances is assessed both generally, applying PMD limit-values of ITU-T, and for a selected transmission link, evaluating numerical simulations using a worst-case simulation model.
