Single Pair Ethernet

Extend data and power to the edge of OT networks


Single Pair Ethernet

The new physical layer technology transforming communications for automation devices

What is Single Pair Ethernet?

Single Pair Ethernet (SPE) is quite simply Ethernet transmission over a balanced pair of conductors. 10Mb/s SPE does some unique things that make it possible to bring Ethernet to the edge of OT networks. IEEE 802.3cg-2019™ standardizes SPE which is designed for 10Mb/s transmission speeds over a balanced pair of conductors. The IEEE standard defines two PHYs - 10BASE-T1L and 10BASE-T1S - which provide SPE communications.


“The benefits SPE can bring to building and industrial automation are exciting. SPE is a vital next-generation technology which stands to help industry achieve better business outcomes through the continuation of convergence across the enterprise.”

—Brett Lane, CTO at Panduit

How does SPE work?

Single Pair Ethernet is a transmission technology built and standardized by IEEE to replace built-for-purpose serial communications.



The new line of Panduit SPE products give customers long-distance reach, simple integration, fast and repeatable installation, and long-term reliability. The first products to market include a shielded connector and single pair cable. These products enable customers in a variety of markets to take advantage of the benefits of Single Pair Ethernet.
