Single Pair Ethernet is a technology that will reduce the barriers to adoption of Ethernet for devices that need both power and limited communications, which often use various 2-wire fieldbus protocols. It operates over a single twisted pair while delivering the full Ethernet stack. Single Pair Ethernet is unique in that it can deliver data with up to 1km reach – and delivering up to 10mbps speeds at that distance, plenty of bandwidth for many devices used in building or industrial automation.
