Abstract

Traditionally, optical networks have been designed with the objective of minimizing the capital expenditure (CAPEX) without considering the operative costs (OPEX), due for instance to energy consumption. However, the increase of energy consumption and corresponding costs and the challenges imposed by the environmental issues (such as the global warming and the limited oil reserves) are demanding for a more responsible energy usage, including in the optical networking field.
