Single Pair Ethernet (SPE) describes the transmission of Ethernet over only one pair of copper wires. In addition to data transmission via Ethernet, SPE also enables a simultaneous power supply of terminal devices via PoDL - Power over Data Line. Previously, this required two pairs for Fast Ethernet (100MB) and four pairs for Gigabit Ethernet. SPE now opens up completely new possibilities and fields of application for industrial Ethernet.
"ONLY THE SPE INDUSTRIAL PARTNER NETWORK WITH ITS NUMEROUS PARTNERS GIVES USERS THE TECHNICAL EXPERTISE TO CONVERT FIELD LEVEL TO SINGLE PAIR ETHERNET."

SPE Industrial Partner Network
Single Pair Ethernet is the infrastructure basis that makes IIoT and Industry 4.0 possible. Seven industrial technology leaders have joined forces to advance the technology for the rapidly growing IIoT market. HARTING, TE Connectivity, HIROSE, Würth Electronics, LEONI, MURR Elektronik and Softing are the founding members of the SPE Industrial Partner Network.
For the reliable establishment of the entire future SPE ecosystem, standards for transmission protocols, cabling and device components are also jointly supported. Therefore, all members of the partner program, as well as the ISO/IEC JTC 1/SC 25/WG 3, are in close exchange and intensive cooperation with IEEE 802.3 and IEC SC46C for uniform transmission standards and copper data cables.
SINGLE PAIR ETHERNET
Single Pair Ethernet allows the barrier-free connection of field devices, sensor/actuator technology and much more. The field level becomes smart and thus reduces the effort for parameterisation, initialisation and programming.
The construction, operation and maintenance of systems becomes more efficient and cost-effective. For the first time, Ethernet can communicate space- and cost-efficiently from the cloud to the field level.
Industrial Ethernet via just one wire pair, known as Single Pair Ethernet (SPE), is becoming more and more popular. Several company cooperations offer solutions on the market for SPE, which makes it clear that there are several standard proposals for SPE mating faces.
There is only one standardized industrial interface, which is the only solution internationally defined for cabling standards and transmission standards. This is where our technology and standards come into play.
In order to make SPE an enabler of the smart field level and the IIoT, a uniform infrastructure is required as well as device components that coordinate with each other and function. Based on a uniform and standardized infrastructure of cables and interfaces, device and chip developers start their work. Only when the networking of the devices is securely guaranteed do they have the necessary security to invest in a completely new market.
