Summary Number of FTTH subscribers World wide 61 million FTTH/B subscribers a t th e en d o f 2010 197 million FTTH/B subscribers expected by 2015. (IDATE, 09/06/2011) 5 to 10 W Typical Typical FTTH power consumption per subscriber = . g e household's p 3.6 to 7.2 kWh per month. 0.8 to 1.6 % of the avera p tion p er month , ower consum which is e.g. ~450 kWh (Kyoto city, 2008). But! 197 million x 10 Watt = 1970 MWatt. Corresponding to four 500-MW power stations. Access and aggregation account ~80 % of the next-generation network.Lower consumption yields longer service life with a back-up battery in case of power outage. Very important in providing the lifeline service Guidelines for power saving Japan y E co l ogy gu id e li ne f or th e ICT i n d us t r Established by ICT Ecology Guideline Council in Japan (Feb 2010). Specifies power consumption guideline for transport equipment - , broadband routers, layer-2 switches, PON equipment and broadband base station equipment. Europe Code of Conduct on Energy Consumption of Broadband Equipment – Version 4 Published by European Commission (Feb 2011). Sets out the basic y all p p p rinci les to be followed b arties involved in broadband equipment, operating in the European Community, in respect of energy efficient equipment. Target power: G-PON/GE-PON ONU Japan GE-PON ONU Figure of merit: P = average energy consumption (W) / GE-PON ONU dle-State: no traffic, On-State: 20 Mbit/s downstream, 5 Mbit/s upstream Target power: G-PON/GE-PON OLT JapanGE-PON OLT, with 1Gbps SNIFigure of merit: E = average energy consumption (W) / total no. of lines Euro Fully equipped with maximum configuration implementing standard Layer-2 (Ethernet) aggregation functionalities, including Multicast Outline 1.
