Single Pair Ethernet (SPE) describes the transmission of Ethernet over only one pair of copper wires. The SPE Industrial Partner Network is an association of technology leaders that promote Single Pair Ethernet as the basis for rapid and successful growth of the IIoT (Industrial Ethernet of Things). For future users we are the first point of contact for all questions concerning the construction of SPE networks and devices. We provide clear recommendations for the development of future IIoT applications and are the central information and exchange platform.
