Connectivity Breakthrough

Single Pair Ethernet

Single Pair Ethernet is a key development and the infrastructure that will make another level of IIoT and Industry 4.0 connectivity possible. For the reliable establishment of the entire future SPE ecosystem, standards for transmission protocols, cabling and device components are all being jointly developed by a broad coalition of industrial automation and control suppliers.

What is Single Pair Ethernet?

Single Pair Ethernet (SPE) is a technology that enables the transmission of Ethernet over only one pair of copper wires. In addition, it enables a simultaneous power supply of terminal devices via PoDL (Power over Data Line) which previously required two pairs for Fast Ethernet (100MB) and four pairs for Gigabit Ethernet. Read in this section how SPE opens up completely new possibilities and fields of application for Industrial Ethernet.
