The Single-Pair-Ethernet (SPE) concept comes from the automotive industry which required lean Ethernet cabling for vehicles. On the basis of xBASE-T1 protocols, SPE can also be used in building cabling and factory automation. SPE requires – as the name suggests – just a single twisted pair for data transmission. A thin two-core cable and a compact connector are sufficient for the cabling. In comparison to classic Ethernet cabling, the number of possible connection points is multiplied. The connection to the Local Area Network (LAN) takes place using switches either centrally in the floor distributor or distributed in the zone at the service outlets.
