The resultant differential signal is then fed into the twisted pair cable through impedance matching resistors. At the receiving end, a single amplifier receives the differential signals and ...

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.

Network Wiring: One Unshielded Twisted Pair 24 AWG (0,5 mm) or thicker. Impedance: 100 ± 20 ohms. Built-in transient protection & ground lifting. Built-in brightness & sharpness controls; blue power ...
