This white paper first summarizes the impact of the increased noise level on standardized systems, and then briefly reviews the history of managing alien crosstalk in BASE-T Ethernet, beginning with IEEE 802.3an-2006 10GBASE-T, and continued in NBASE-T and IEEE 802.3bz-2016 2.5G and 5G BASE-T technologies. Finally, it presents the observed problem of higher power using the nonstandard implementation vs. standard IEEE 802.3bz 2.5Gb/s and 5Gb/s on three test setups including 6-around-1 bundled cables.Download Here
