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

View on HN

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.

-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)

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.

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

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

Lol these youngsters with their little plastic plugs. 10Base5 is where it's at. Or 10Base2 if you want to be cool.

Intended as /s but I actually still have some stuff here that I need to use a 10BaseT AUI transceiver on :) I love old hardware.

I have a 10base-5 AUI on my desk. Makes an interesting conversation piece now and then.

I’d you haven’t used a drill to attach a computer to a network, you can’t appreciate how easy things are these days…

I remember when 10BASE-T was brand new and hilariously fast and radically better than the clumsy, bulky connectors and cables that had preceded it.

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?

Yes, and 100BASET as well.

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!?

"The 88Q4364 is manufactured using a standard digital CMOS process and contains all the active circuitry required to implement the physical layer functions to transmit and receive data on a single balanced twisted pair."

ez just use PAM4 signaling

(/s)

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

A "Fresh prince" moment.

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