Energy consumption analysis of real metro-optical network

Significant part of the total energy consumption in distribution and core optical networks is contributed by the energy consumption of Internet Protocol (IP) routers. In this paper, an energy efficiency analysis has been performed for the case of real metro-optical network of a medium size city. Two real metro-optical network configurations, mores specifically dark fiber and the dense wavelength division multiplexing (DWDM) have been analyzed in terms of the energy efficiency. Obtained results provide insight into daily variations of routers’ energy efficiency expressed in watts (W) per Mb/s of transferred traffic. In addition, cons and pros for selection of analyzed network configurations in real metro-optical implementations have been presented from the point of energy efficiency.
