Single Pair Ethernet is becoming increasingly popular in industrial networking because it simplifies cabling to just one twisted pair. When power is delivered over the same pair, the SPE standard with Power over Data Lines (PoDL) offers an exceptionally streamlined solution—although its implementation is not trivial. The Würth Elektronik (WE) reference design for Single Pair Ethernet (SPE) with Power over Data Lines (PoDL) demonstrates how to implement this technology effectively.
