Single Pair Ethernet

Should the number of devices in a zoning increase so much, that existing RJ45 connectivity will not be enough, IEEE defined a Single Pair Ethernet System to further increase port density.

New technology for ALL-IP

A network technology with revolutionary potential is currently developing: Single Pair Ethernet (SPE). Several standardization committees and industry consortiums are working on defining how this application will be used in the future cabling environment. R&M is participating in a leading role in it. SPE, based on IEEE’s xBASE-T1 technology, uses a single twisted pair for data transmission and miniaturized connectors. SPE can replace the traditional field bus, helping realize high density, fast connections, and ease of installation. SPE has the potential to quickly become a key technology in the Internet of Things (IoT) and Industrial Internet of Things (IIoT).

Complementing the Digital Ceiling

R&M considers SPE as an ideal addition to the existing digital Ceiling concept. Should the number of devices in a zoning increase so much, that existing RJ45 connectivity will not be enough, the Single Pair Ethernet System can further increase port density. Since SPE is potentially smaller, denser, and more cost-effective it can complement the existing Digital Ceiling infrastructure for the last few meters to connect to the devices. Due to the limited bandwidth and its application-specific nature, SPE will probably not replace the generic cabling, but will mostly be used for point-to-point connections to devices on demand.

Single Pair Ethernet System Alliance

To further coordinate developments in the field of SPE, R&M participated in founding the “Single Pair Ethernet System Alliance” with other leading technology companies from different technological backgrounds. R&M also participates in the TIA-organized, US-based SPEC consortium. In these organizations, SPE expertise and knowledge are bundled and exchanged in an open way to promote the technology independent of specific company solutions.

SPE connectivity choice

Multiple proposals have been made over the past few years for SPE connectivity. Currently, 6 variants are standardized in IEC 63171 detail specifications with emphasis on different features. Some application bodies already made selections from this set of connectors for their respective specifications. However, since the selection process often was somewhat political and not merit-based, the final decision is still out on what design(s) will finally win the race.

In building automation, R&M considers the interface IEC 63171-1 (LC-copper style) the most promising candidate. R&M offers a complete portfolio for the IEC 63171-1 interface.
