Long reach, single-pair Ethernet, 10BASE-T1L physical layer devices are proving a game changer on the road to realizing the vision of seamless connectivity. By extending Ethernet connectivity to edge nodes in remote and distant locations, this technology is enabling new data streams, additional process variables, and auxiliary measurements to be communicated. The IEEE 802.3cg™-2019 standard governs 10BASE-T1L connectivity. It is a single-pair Ethernet (SPE) media standard, providing for 10 megabits per second communication and it enables both power and data over single twisted pair cabling up to 1 km. 10BASE-T1L connectivity promises to extend the benefits of IIoT to the remote corners of factories, building and process plants, and even into hazardous locations where sensors and other endpoints had, until now, limited connectivity.
