From copper to fiber in the Italian loop network architectures, economics, deployment strategies

摘要

This paper deals with the modernization of the Italian access network and in particular with the introduction of optical technologies into the subscriber loop plant. An overview is presented of the chosen network architecture and the pursued evolution approach, as based on strategic motivations, available technologies and relevant cost profiles. the economics of the copper-to-fiber transition is also addressed, and the short-mid term deployment steps are outlined.
