10BASE-T1S is Single-Pair Ethernet with 10 Mbit/s for short distances and multi-drop topologies.

10BASE-T1S is a 10 Mbit/s Single-Pair Ethernet variant for short distances and multi-drop topologies in the vehicle. It was created to bring Ethernet all the way to the edge of in-vehicle networks while allowing multiple transceivers to operate on a shared bus line. This is particularly interesting for sensors, microphones, speakers, and body or infotainment-related nodes in zonal architectures.
