The IEC SC 48B Standards Committee for Copper Connectors recently published the IEC 63171-6 standard that describes the T1 Industrial Style SPE plug-in face – the future interface for single-pair Ethernet applications in industry. This standard is supported and integrated by the SPE relevant standards ISO/IEC 11801-3, ANSI TIA 1005-x and IEEE802.3cg.
IEC 63171-6 is included as a complete standard document with all specifications and test parameters in ISO/IEC 11801-3 for cabling and represents the specified standard interface. According to IEC, it is still possible to use cabling components other than in IEC 63171-6, but these are not compliant with the standard and may pose a risk of functional loss.
For this reason, ISO/IEC JTC 1/SC 25/WG 3 started an international selection process in 2018, at the request of IEEE 802.3, which gives a recommendation for a SPE Media Dependent Interface (MDI). As a result of this choice of over 20 standardisation bodies, a mating face has prevailed for industrial applications (M2I2C2E2 and M3I3C3E3 environmental protection levels) according to IEC 63171-6.
Single-pair Ethernet is the infrastructure basis that makes IIoT and Industry 4.0 possible.
