Abstract :
Based on the simulations of realistic network conditions, this paper analyzes the network-cost dependence of the following parameters: the reach, the presence of optical add-drop multiplexers (OADMs) and branching nodes, and the chromatic dispersion. Trends and guidelines for the determination of the best match between system specifications and optimum network cost are proposed. The performance and cost impact of electrical and optical methods are critically analyzed.
