Abstract [en]

This document contains the final report of the thesis project: ATM based passive optical networks (ATM PONs). PONs are being tried as a method of extending optical fibres into the access network. PONs offer the ability of sharing the transmission costs of the access network amongst a large number of customers by allowing fibre and bandwidth sharing via passive optical splitters. ITU-T recommendation G.983 defines a specification for ATM based PONs. An SDL model was used in the project to investigate the possibility of using the Ericsson ATM switch (AXD 301) as the head-end in a G.983 compliant PON (i.e., the OLT). Also some simulations was made, using SDT. The results indicated that the ATM switch could very well serve as an OLT (by addition of a connection board). It was concluded that although the complexity of the system is quite high (caused by the TDMA technique used), it is a feasible solution. A techno-economical analysis made in the initial part of this project indicates that PONs are too expensive for deployment in the near future, compared to enhanced copper networks using xDSL technology. However, new applications could boost demand for high bandwidth sooner than expected. In any case, PONs (except in the FTTH configuration) constitute a natural upgrade for enhanced copper networks.
