Twisted pairs support less bandwidth than coaxial cable or optical fiber. Twisted pair cables are available unshielded (UTP) or shielded (STP), with UTP being the most common. Shielded twisted ...

Today's twisted-pair copper ethernet data busses are maxed ... and other data is being sent between continents over fiber-optic cables today, so the distance thing is no sweat for this technology.

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.

For equipment that supports SFP modules, it’s even possible to switch its interfaces between copper-based twisted pair and fiber-optic versions, which at least saves the trouble of replacing the ...
