1000BASE-T1 is the Gigabit variant of Automotive Ethernet over a single twisted pair.

1000BASE-T1 is the Gigabit variant of Automotive Ethernet over a single twisted pair and is used when 100 Mbit/s is no longer sufficient. It is particularly relevant for data-intensive applications such as high-resolution cameras, powerful domain or zonal architectures, and fast backbone connections. For loggers, 1000BASE-T1 is important because many modern in-vehicle Ethernet links operate exactly in this range and therefore require suitable taps, converters, and interfaces.
