The paper will provide a detailed technical overview of the validation of achieving 40 Gb/s and 100 Gb/s Ethernet over 10 meters of passive twinaxial copper cable assemblies. The copper media specifications will be explored in detail including an overview of the specification development analysis methodologies and test fixture specifications. Comparisons of 40GBASE-CR4 and 100GBASE-CR10 to other 10 Gb/s copper physical layer types such as 10GBASE-KR (Clause 72) "Backplane Ethernet" and 10GBASE-CX4 "Ethernet over twinaxial cable assemblies" will be explored to illustrate the evolution of IEEE 802.3 copper channel specifications most notably the replacement of insertion loss to crosstalk fit functions and limit lines with integrated crosstalk noise ratios.
