Riassunto
In this Thesis, after a brief overview on what PON is and on its actual technologies of implementation, a hybrid WDM/TDMA-PON system will be analyzed, focusing the attention on the receiver at the optical line terminal.
The aim is to demonstrate the main advantages of the proposed system respect to a traditional approach:
• Better sensitivity particular useful with the hybrid approach by using the coherent receiver at OLT.
• Phase recovery capability by using simple linear combiner circuit, AC coupling and differential encoding.
• Reflection noise suppression with AC coupling and Manchester coding.
In order to highlight these characteristics,a numerical simulator for a hybrid WDM/TDMA-PON using self-homodyne and differential coding was devoloped and the obtained results are reported in chapter 3.
