Project's description

The undertaken work was concerned with the performance analysis of dense WDM (DWDM) systems and all-optical transport networks with optical dispersion compensation (ODC).

The objectives and contributions of the project were:

1. development of analytical formulation for performance evaluation of arbitrary optical filters;
2. performance evaluation of various coding formats for DWDM systems which allows to assess the advantages / drawbacks of using those coding formats in DWDM systems;
3. performance evaluation of several ODC strategies in dispersion supported transmission (DST) and conventional systems and assessment of limitations imposed by polarisation mode dispersion on the performance of DST DWDM/ODC systems;
4. generalisation of analytical formulation for the assessment of cross-phase modulation influence on the DWDM/ODC system performance;
5. assessment of limitations imposed by fibre transmission and nodes on the size and design of DWDM/ODC networks, using the rigorous formulation developed in topics 1) and 4).
