“…The environmental impact of the network's energy consumption is not negligible either, as its current carbon footprint equals that of the airline industry, and it is likely to further increase. In recent years, the scientific community initiated research on network energy consumption [1], [2], [9], [10]. Recent papers analyze and model the energy efficiency of the network and its components, provide insight into the nature and lower bounds of energy consumption in communication networks, and present more energy-efficient networking gear and network architectures.…”

Abstract-Energy consumption of customer premises equipment (CPE) in the new generation of time-division multiplexing (TDM) passive optical networks (PON) operating at 10 Gb/s, has become a serious problem both in terms of the global network energy consumption and the CPE battery life. The proposed low energy passive optical network (PON), based on a novel bitinterleaving downstream protocol, reduces the protocol processing energy by a factor of 30 and enables a significant reduction in the total CPE energy consumption over the standard 10 Gb/s PON CPE. The network architecture, protocol and the key enabling techniques for its implementation, including dynamic traffic interleaving, rate-adaptive descrambling of decimated traffic and downsampling clock and data recovery (CDR) circuit, are described. Detailed analysis of the CPE energy consumption and comparison with the standard PON CPE is also included in the paper.
