IEEE Tech Talk: Single Pair Ethernet

New IEEE 802.3 standards and technologies deliver power and data over a single pair of wires to address the challenges of ‘operational technology” (OT) automation applications and simplify OT networks. This talk will explore some of the unique features and reasons for Single Pair Ethernet’s growing adoption in the OT space leveraging modern technology to revisit core Ethernet features and speeds suitable for automation and control applications.

White Paper: Single Pair Ethernet – The network infrastructure for Industry 4.0

Experts consider Single Pair Ethernet to be the next generation of communication architecture in automation. The concept behind it is essentially an extension of the Ethernet to the sensor, that is wherever “tracks” (in the literal sense) rather than data highways are needed in every inch of space within the plant – it is compact, flexible and offers extensive reach.

SPE and Smart Buildings: A Smart Pairing

Fieldbus applications have developed over the past decades from simple analog communication to digital communications over serial networks. These serial networks often operate over a single twisted pair. With the increasing scrutiny on security of fieldbus systems and the increasing desire to simplify the data flow from sensor to cloud, the advent of Single Pair Ethernet technology seems both well-timed and well-planned. Single pair cabling with LC-style connectors make sense, adding simplicity and reducing time to work for data transmission to the edge.
There are four areas where SPE generally can match or improve upon fieldbus technology: topology, security, power, and data.

Two Connector Types for Single Pair Ethernet

Single Pair Ethernet will become a key technology in smart buildings. It is the missing link for connecting devices up to sensor/actuator level by means of a standard Internet protocol (IP). It has the potential to replace existing field bus systems in the Internet of Things (IoT) in buildings or the Industrial Internet of Things (IIoT) in smart factories.

IO-Link and Single Pair Ethernet, two recent networking protocols for improved industrial connectivity

single-pair Ethernet takes the enterprise-class networking protocol and implements robust and reliable device communication over a single twisted pair. Reducing the number of pairs by a quarter reduces cable weight, reduces cable cost, and uses robust industrial-grade widely available connectors. Unlike the serial-based IO-Link, SPE functions as a standard networking protocol and can operate over distances of up to 15 metres using unshielded cables and 40 metres using shielded cables.
