Shielding of individual signal or power pairs is
not required because most V1.0 controllers and
transceivers are DC-coupled. The overall AUI
cable shield provides for shielding and grounding
and is connected to pin 1 and the AUI connector
shell.

In practice, most Ethernet V1.0 equipment uses
version 2.0 cables due to cross-talk problems
caused by the lack of individual shielding of the

Wire Sizes
The three versions of AUI cables also use differ-
ent wire sizes for the signal and power pairs.

transceiver cable uses.
