“Single-Pair Ethernet is a new-to-the-world technology that is a game-changer for building systems cabling, where the bandwidth requirements aren’t as demanding as data communications but there is still a need for a single network to support many disparate systems.”

– Lindsey Parker, Manager, Business Development at Panduit

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.

How does SPE work?

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

SPE as Data Transport for OT Networks
Compared to using traditional field buses, using an Ethernet architecture simplifies system implementations since a single software framework can be used from the lowest to the highest speed ranges.
