Power consumption of wired access network technologies

Wired broadband access can be realized using various technologies, configurations and protocols. It is widely deployed and able to provide both high data rates and high reliability. These features are of strong importance for many advanced applications. Since the number of broadband subscribers worldwide grows exponentially, the power efficiency of access networks becomes an important issue. The main goal of this paper is to study the power consumption of different wired broadband access technologies including both those already widely used and those which are state-of-the art, but not yet widely deployed. Thus, results on power efficiency of different access networks such as hybrid fiber coax (HFC), digital subscriber line (DSL), 1 Gbit/s and 10 Gbit/s point-to-point Ethernet and passive optical networks (1G-PON and 10G-PON) are shown.
