An Approach for Backbone Upgrading Technology Selection Based on Techno-economic Evaluation Model

Abstract

In this paper comparison and evaluation of the technologies for delivering broadband services at the metro and backbone level is presented In particular, the paper deals with study and techno-economic analysis of two key broadband technologies used for upgrading metropolitan and backbone networks: the SDH and WDM. The study performed is based on calculations of two indexes: CAP EX and OPEX calculations. The studied case is the Telecom Slovenia network which is the incumbent operator in Slovenia. The study is based on the data supplied by the operator.
