Network equipment manufacturers and communications chip developers are actively building products for the emerging higher speed Ethernet (HSE) market. HSE is being driven by the new IEEE P802.3ba draft standard for 40 and 100 Gigabit Ethernet. Early HSE technology adopters require layer 1 and 2 test equipment early in 2009. This booklet provides insight on the 802.3ba standard and demonstrates layer-2 and sub-layer 2 Ethernet test methodologies.
