Performance of WDM transimission network

The growth in demand for multimedia services necessitate the development of a high capacity information network in Saudi Arabia. Such network should provide high quality multiservices to schools, hospitals, and government agencies. We assess the performance of three different WDM systems. Two network configurations of 32 and 64 channels each transmitting at 10 G bit/s and one network configuration of 32 channels at 40 Gbit/s are studied. The performance of the various configurations of the core network is also compared.
