Single Pair Ethernet System Alliance – Technology for the Future
The Single Pair Ethernet System Alliance is a worldwide association of leading technology companies. We want to implement and further develop the pioneering Single Pair Ethernet technology. Together and holistically.
One for all. All for one.
The Single Pair Ethernet System Alliance stands for the planning and future security of this new technology. The companies in the alliance contribute themselves and their experience. And they participate in the exchange of know-how between the different industries. Interesting for you?

REVIEW: PAN-EUROPEAN DESIGN CONFERENCE
The Pan-European Electronics Design Conference (PEDC) 2026 in Prague was a resounding success for us. With a keynote speech followed by a panel discussion, we were able to impressively demonstrate how SPE is shaping the future of networked systems – and how great the interest in end-to-end, IP-based architectures from sensor to cloud has become.

Single Pair Ethernet is gaining serious momentum in the US
At a BICSI Winter panel in Orlando, Florida (USA), “Why Single Pair Ethernet is Ushering in a New Era” drew a nearly full room — a clear signal that SPE is shifting from discussion to deployment and rapidly expanding its US market footprint.
“Huawei is convinced that new technologies can only be successfully developed through the global co-operation of many partners. We are therefore delighted to be able to make a contribution to the Single Pair Ethernet System Alliance.“
Dr. David Lou, Chief Researcher, 2012 Labs, Huawei Technologies
“Single Pair Ethernet is the ideal infrastructure for the IIOT. It offers barrier-free communication from the sensor to the cloud and can therefore realise enormous efficiency and cost-saving potential.”
Simon Seereiner, Business Development Manager Single Pair Ethernet
“For plant engineers, single pair Ethernet is a labor saver. Installation is simpler compared to four-pair Ethernet and allows a noticeable reduction in space and weight.”
Karola Tillack, Leader Division Device & Field Connectivity at Weidmüller
“Our cooperation in standardization creates security. Users around the world can build efficient network and cabling structures based on standardized interfaces, from the sensor through the control and enterprise levels to the cloud.”
Torsten Janwlecke, President Business Area Device Connectors at Phoenix Contact
“Compact design, miniaturized dimensions, a significant reduction in weight and the ease of connection also make SPE technology interesting for automation technology, building cabling, railroad technology and many other applications.”
Florian Gärtner, Managing Director Telegärtner Karl Gärtner GmbH
“Single Pair Ethernet opens up new fields of application for users in industrial networking: right down to the actuator and sensor level. The advantages lie in the standardized interface and the optimized structure of the SPE connection solutions.”
Folke Michelmann, Executive Vice President Business Area Medical & Industries at Rosenberger
