IEEE 10Base-T1

10Base-T1 is an Ethernet interface for 10 Mbit/s that uses single-pair STP cables. The concept is Single-Pair Ethernet (SPE) and is used in automotive Ethernet

and industrial automation.

10Base-T1 is specified by the IEEE working group 802.3cg and uses a single twisted-pair wire as the transmission medium

over which the transmit and receive signals are transmitted infull duplex. In addition, the supply voltage for powered devices (PD) such as sensors, actuators, card readers and the like can also be routed via the wire pair. This is supported by Power over Data Lines

(PoDL), which can transmit up to 50 W. The data rate supported by 10Base-T1 is 10 Mbit/s, and the bridgeable distance is 1,000 m. The SPE cabling consists of a symmetrically shielded pair of wires with a bandwidth of 20 MHz.
