You're still talking about a cable. The cable may be compatible with those standards, but you can put anything through it. It's just a physical connection.
>And people nerdy enough to run 10GE at home might well run fibre. So, no, the specifity is needed and useful.
No, because if you say "which do you want? Ethernet or fiber?" no one will look at you like if you asked if they want salt or beef. It's technically incorrect, but everyone will understand what is being asked.
If you want to ackshually, the post I was replying to was talking about what "devices use" and cables required for that, so it's in fact about what standards these devices support.
Apart from that, again, in the context of 10GE you can by no means assume copper when talking about an Ethernet port; SFP+ slots are quite common. Your assertion that "everyone will understand" is also something I plainly know to be untrue in my bubble. It may be true in the context of slower speeds, but for ≥10GE the general performance characteristics of twisted-pair copper transceivers are so bad as to make it into the crossover point from copper cabling into DAC cables and fibre.
And, honestly, the assumption that "Ethernet = copper cabling" is harmful for 10GE. Those transceivers are hot garbage in the literal sense, they run hot enough to warrant usage limitations on switches due to cooling/overheating limits, and they tend to be quite picky about cable quality on establishing links.
Yes, that person said "most devices use Ethernet", to which you correctly pointed out they meant to say RJ45. However, in the process of making that correction you made an unrelated error yourself in saying that fiber is Ethernet too.
>you can by no means assume copper when talking about an Ethernet port
You can, if by "Ethernet" you mean an RJ45 jack and its cable, which is a fairly common usage of the word. It doesn't matter that it's technically incorrect. The default idea of physical protocol that the word "Ethernet" invokes in most people is that of twisted pair copper cabling. If you take a random person and put in front of them a fiber optic cable carrying Ethernet and a copper cable carrying serial signals and tell them "would you mind unplugging the Ethernet cable?" they'll disconnect the copper cable.
>Your assertion that "everyone will understand" is also something I plainly know to be untrue in my bubble.
Oh, so you know several people who when presented with the dichotomy of Ethernet or fiber (because that's what the comment you replied to was about, as it put Ethernet in contrast with fiber), they'll be completely dumbfounded about what is meant, as if hearing gobbledygook?
Yes.
And I've used up the time I'm willing to sink into this subthread, see you around.
