Background
Power over Ethernet (PoE) technology refers to a technology for supplying Power through a plurality of twisted pairs of voice, data, and video, which are commonly used. The 2016 IEEE introduced its Power over data line (PoDL) standard, 802.3bu-2016, for automotive, industrial automation, air and rail transport, and other situations where 100BASE-T1, 1000BASE-T1, or any single twisted pair data or non-data entity protocol is employed, and possibly other situations in various industries where the Internet of things (IoT) evolution needs to be accommodated through upgrades. In 2019 IEEE has defined a new Ethernet standard, IEEE802.3 cg-2019, for 10Mb/s operation and power transfer over a pair of balanced conductors. Since a single pair of cables can now support both data and power, using this standard can save significant costs and be easier to install in building automation applications.
