Computer networks are one of the major slices of the global energy consumption. Since 2009, a couple of standards have been developed for energy conservation in passive optical networks. These standards and most of the researches are based on improvements on Optical Network Unit side. In this study, a novel energy efficiency algorithm, which is based on coupling two Optical Line Terminal to reduce energy consumption in central office, is proposed. Our design employs optical switches and amplifiers to create a switch-box, which is under control of both Optical Line Terminal pairs.
