SPE - One Wire Pair - An Infinite Number of Applications

Single Pair Ethernet (SPE) sets new standards in intelligent communication architecture. Using power over data line (PoDL), parallel high-performance data and power transmission is supported via just one Ethernet wire pair.

Originally developed for automotive applications, SPE now delivers the perfect balance of speed, distance and power delivery for a wide variety of IoT projects. Based on familiar Ethernet and TCP/IP protocols, SPE extends the reach of Ethernet to everywhere - including those sensors in the most remote corners of the plant or out in the field. PoDL ensures sufficient wattage output is readily available for powering numerous IoT components and sensors.


From the Sensor to the Cloud

Traditional Ethernet solutions are undergoing a rapid transformation, driven by the increasing automation and digitization of industrial plants. This is demanding connections that are not only fit for purpose but also future-proof. With SPE you can be confident that your cabling deployments will stand the test of time for many years to come.

From the sensor to the cloud, SPE ensures a continuous and reliable connection. For every application, whether in industry, logistics, buildings, wherever data is generated.


Standardization - The Key to Success

Rosenberger has joined forces with renowned manufacturers from the connector, industrial automation, technology, and cabling industries to develop an international standard: Because interoperability and the long-term success of SPE can only be ensured with manufacturer-independent standards.

The following standardization variants are currently being jointly developed: IEC 63171-2 for IP20 and IEC 63171-5 for IP67.

Whitepaper: Ethernet in the Automotive World



  • Single Pair Ethernet (SPE) connection enables uniform Ethernet-based communication - from the sensor to the cloud
  • A key enabling technology for industry 4.0 and IIoT
  • Low cabling costs due to use of existing cabling infrastructures
  • Can be used across applications with ranges of up to 1,000 m
  • Transmission characteristics of up to 1 Gbps
  • Ideal for weight and space constrained environments
  • Reduces total installation costs


Driven by the increased networking requirements of IIoT and Industry 4.0, the ideal solution for wired communication infrastructure with single-pair Ethernet is the combination of high transmission performance and space and weight.
