An idle Ethernet link is constantly transmitting a carrier signal from both ends. (This is true for the 1xBASE-T point to point Ethernet. Old, unused coax shared medium standards do the no carrier thing.) | |

| Jan 2, 2013 at 18:20 | comment | added | longneck | Ethernet is transmitting all the time, even when there is no data to send. Hence the (comparatively) small difference between the idle current draw and the active current draw. | |
