But Ethernet didn’t start with twisted pair cable. [Mark] and [Ben] at The Serial Port YouTube channel are taking a deep dive into the twisted history of Ethernet on twisted pair wiring.

A thin-diameter wire (22 to 26 gauge) commonly used for telephone and network ... in 1881. Twisted pairs support less bandwidth than coaxial cable or optical fiber. Twisted pair cables are ...

while requiring just the single twisted pair cable when adding Power over Data Lines (PoDL). Whereas Power-over-Ethernet (PoE) uses its own dedicated pairs, PoDL piggybacks on the same wires as ...

In some cases, these cables have been used in legacy communication systems and are ... physical layer for long-reach Ethernet communication over a single twisted pair independent of the application.
