Single Pair Ethernet Standard

The Single Pair Ethernet standard gives users investment security. Learn more about the important standards for Single Pair Ethernet.

Barrier-free data transfer between Clould and field level - Single Pair Ethernet is changing industrial communication. To make SPE technology widely available, the compatibility of devices, cables and connectors is a top priority. This is ensured by international standardization. Learn about the important standards and norms for the construction of Single Pair Ethernet networks.


Single Pair Ethernet Standard: IEC 63171-6

With the publication of IEC 63171-6 in January 2020 by the IEC standards committee SC 48B for connection technology, the Single Pair Ethernet standard has been set. The mating face standard IEC 63171-6 T1 Industrial Style was the first standard submitted by HARTING to SC 48B for a Single Pair Ethernet mating face as early as 2016. The publication of this standard gives users a reliable investment basis for future-proof IIoT networks based on Single Pair Ethernet.

IEC 63171-6 (Industrial Style) is a complete standard document with all necessary specifications and test sequences, which is incorporated into current SPE cabling standards of the ISO/IEC 11801-x series of standards for structured cabling.

The implementation of SPE in the ISO/IEC 11801 documents is very important because only in this standard, the cabling channels are described with all necessary parameters (length, number of connections, bandwidth and the complete set of transmission parameters including NEXT, FEXT, shielding properties etc.) with relation to the environment - MICE and can therefore be metrologically verified after installation.


Clear guidelines for users

This connection of component standards to connectors and cables provides all users of SPE with clear guidelines for the construction and testing of appropriate transmission links.

The use of cabling components other than those described in ISO/IEC 11801-3 Amd.1, for example, is possible in principle, but then they no longer conform to the standard and carry the risk of incompatibility and loss of function. For this reason, ISO/IEC JTC 1/SC 25/WG 3 and TIA TR-42 launched international selection processes at the beginning of 2018 to define uniform interfaces. These two selection processes were co-initiated by IEEE 802.3, which requested a recommendation for a SPE Media Depended Interface (MDI) from ISO/IEC and TIA.

More than 20 national expert committees participated in this selection process. As a result of this selection process, the mating face according to IEC 63171-6 based on the proposal from HARTING T1 Industrial has become generally accepted for industrial and industry-related applications (M2I2C2E2 and M3I3C3E3).


Consistent unity via SPE interface

The selection process for TIA TR-42 has confirmed the results of ISO/IEC; there is thus a high level of global agreement on the SPE interfaces. These selected mating faces will now be incorporated into the respective international cabling standards. IEEE802.3 has also defined this SPE interface in the IEEE802.3cg as a recommended Media Dependent Interface (MDI).

With IEC 63171-6, the last building block for a consistently standardized SPE infrastructure has now been set. IEC 63171-6, IEEE 802.3cg, ISO/IEC JTC 1/SC 25/WG 3 and TIA TR-42 stand for the T1 Industrial Style as industrial SPE interface.



Global technology leaders stand behind IEC 63171-6

Founded in 2019, the SPE Industrial Partner Network, a global association of renowned technology leaders, stands united behind the IEC 63171-6 standard and offers the emerging Single Pair Ethernet user group a broad investment basis for IIoT networks on SPE basis.
