Abstract
SDH (Synchronous Digital Hierarchy) is the standard technology for the information transmission in broadband optical networks. Unlike the Internet, SDH networks are strictly planned; rings, meshes, stars, or tree-branches topologies are designed to connect their basic elements. In spite of that, we have found that the SDH network operated by Telefónica in Spain since 1992, shares remarkable topological properties with other real complex networks. In fact, we have found the fingerprint of the so called complex networks such as power-law scaling in the degree distribution and properties of small world networks. In this communication we present an ad hoc model to describe the complex topology found in the Spanish system. The model considers real planning directives and geographical and technological variables. The topological properties of the networks generated by the model are in good agreement with the Spanish SDH network.
