摘要：The paper presents a model used for improving the energy efficiency of dense fiber optical networks present in large metropolitan areas. By reducing energy consumption the OPEX (Operating Expenditures) is decreased offering thus competitive advantage to network opera-tors. The proposed model uses a genetic algorithm approach in order to obtain viable net-work topologies that have the highest degree of robustness while minimizing energy consump-tion.
