Abstract :
This paper describes the technical issues of access and metro networks based on wavelength division multiplexing (WDM) and spectrum slicing technologies, some solutions, proposed. A WDM ring access network with tunable optical network units (ONUs) is proposed. For optimising the system, many parameters (code type, bitrate, tunable filter bandwidth, multiplexer bandwidth, ...etc) are studied. The quality of the received signal is characterised by the simulation of bet error ratio BER. Four remote nodes with four ONUs are studied and simulated with different distances between the centre node and RNs. Therefore the maximum distance can be achieved to 60 km by keeping BER under 10-9.
