Energy Efficient Optical Network – An Implementation Perspective Survey

Abstract

Due to the fast growth of energy consumption in modern industry especially the Information and Communication Technology (ICT) society, many attentions are focused on better energy efficient solutions. In this paper, we provide an implementation perspective survey on employed optical network technologies’ power consumption features. We investigate major techniques of current optical network and corresponding energy consumptions. Some promising techniques are proposed including burst switching, multiple granularity traffic grooming, unified control plane and Green PON to achieve energy efficiency.
