I read the this as 10GBASE-T and for a brief moment in time my whole world turned upside down.

Same. But still... 10BASE-T with 2 wires is a hell of an achievement.. Now 10GBASE-T with two wires, is the "Dark Souls on Bongo Drums" of networking.

  10BASE-T only uses 2 wires to xmit doesn't it?
  - Moto7451 4y ago
    Yes, and 100BASET as well.
  - squarefoot 4y ago
    10BASE-T and 100BASE-T require 2 wires to transmit and 2 wires to receive, 4 wires total. Actually it is better to call them 2 pairs since it's a balanced arrangement in which each pair signals come and go in reverse phase from the interface transformers and wires of each pair are twisted together so that any picked up noise can be canceled out. 1000BASE-T (Gigabit Ethernet) uses all four pairs, that is, all eight wires of a CATx cable.

      There is also 10BASE-T1 and 100BASE-T1 which only requires a single twisted pair for transmit and receive.

        And, as a earlier poster explained, there is 10GBASE-T1, which is 10G over a single pair! Wow! Who knew!?

      ez just use PAM4 signaling (/s)

  10GBASE-T1 does actually exist! It's an automotive standard like 1000BASE-T1

Yeah, I was shocked when I first read it, and then reread seeing no G. I'm not old enough to have liven when 10BASE-T was mainstream.

  Is that the one that used the nasty vampire taps, or am I thinking older.

    That was 10BASE5 aka thicknet: https://en.wikipedia.org/wiki/10BASE5 https://en.wikipedia.org/wiki/10BASE5

    -T indicates "twisted pair". Vampire tap was 10BASE5 (later also called Thick-Ethernet, to contrast with 10Base2 "Thinnet" which used thinner coax and BNC T-pieces)
    - bluGill 4y ago
      I never saw 10base5 coax, but I worked in a lab in the day with massive thick 15 pin cables everywhere (AUI?), and 4 port hubs (that is combine 4 computers into one uplink that I supposed eventually went to coax in the ceiling, though I only saw it go to yet another such hub. The office was 10baseT already, but the lab had a lot of older computers.

  10BASE-T1 is becoming quite popular with industrial / sensor networks these days.

Exactly the same. I read it as 10GBASE-T and my eyebrows hit my ceiling.
