Transceiver Cables

This section explains the signal differences among the various types of AUI transceiver cables. It also explains wire sizes and the proper pinouts for Ethernet Version 2.0 and IEEE 802.3 AUI cables.

Signal Differences

Signal differences occur between different types of transceiver cables because there are three Ethernet standards:

V1.0

V2.0

IEEE 802.3

These three standards also affect the shielding and grounding of the cables and the size of the wires used in the cables.

The most significant difference among AUI
