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.
The Ethernet Alliance has launched a new industry focus around Operational Technology (OT) networks found in building and industrial automation. With the development of Single-Pair Ethernet (SPE) creating new opportunities for solving challenges in OT networks, the Ethernet Alliance says it is seeking to connect with more expertise in the building- and industrial-automation industries.
New IEEE Std 802.3ca™ was approved by the IEEE-SA Standards Board on June 4, 2020. The standard defines two Physical Layer (PHY) specifications that support 25 Gb/s and 50 Gb/s EPON operation over a single strand of single-mode optical fiber and calls out two new EPON architectures — 25G-EPON and 50G-EPON.
The IEEE 802.3cg standard is a single-pair Ethernet standard that that supports speeds up to 10 Mbps and extends Ethernet range up to 1,000 meters. Learn about 802.3cg’s two link-layer standards, 10Base-T1S and 10Base-T1L, and what they mean for IoT and automotive applications.
The standards development efforts that will produce specifications for single-pair data transmission and single-pair cabling systems will build on a vehicular-related foundation. In 2015 the IEEE completed its 802.3bw standard which specifies 100Base-T1 systems, driven by the automotive industry’s needs.
The IoT Community and the IEEE IoT Initiative are collaborating on activities to help accelerate the digital transformation of the Industrial Internet of Things (IIoT) and to speed the development of IoT for broader adoption across enterprise and industrial sectors. They seek to create a common industry language and framework in the areas of: Industrial IoT and Manufacturing; Smart Cities; Precision Agriculture; Healthcare; Security and Privacy; Computing and Information Processing; Communications and Connectivity, and other areas.
In 2017, the IEEE-SA Standards Board approved IEEE Standard 802.3bs. This resulted in the official launch of 400 Gigabit Ethernet. In theoretical terms, it is the advancement from 100G Ethernet and can operate four times faster than 100G. Not only is this, but it also offers a denser configuration and a better economy of scale. Unlike 100G transceiver modules, the 400G transceivers come with 8 channels and utilize PAM4 encoding to accomplish 50Gbps per channel.
