"The present document defines the metric@ methodology and the test conditions to evaluate the Equipment Energy Efficiency Ratio (EEER) of Transport equipments. The Transport equipments covered will include all the transmission equipment connected to the network by means of wired medium (i.e. copper or fiber)@ typically running at the network OSI level 1. The present document also covers the equipment running at the network OSI level 2 (e.g. MPLS-TP) that are not included in the ETSI standard on ""Measurement Methods for Energy Efficiency of Router and Switch Equipment"" (the same approach is followed by ATIS standard on Transport equipment@ see ATIS-0600015.02.2009 [2]). The present document is not applicable at node etwork level but only at equipment level. Examples of typical wired Transport equipments covered by the present document are switches or crosses connects (SDH@ OTN) and add/drop multiplexers (DWDM). The present document covers also simpler systems as multiplexers/demultiplexers (DWDM)@ optical amplifiers@ transponders. Transport equipments that exploit radio or wireless interfaces (e.g. free space optics and point to point wireless/microwave transport) are out of the scope of the present document. It is highlighted that ATIS standard for transport equipment [2] includes wireless transport equipment."
