Ports and Cabling for 10 GbE, 25 GbE, 40 GbE, 50 GbE, 100 GbE

Question. Getting back into networking after 4 year break doing storage.

What are the port and cabling options for:

  • 10 GbE?
  • 25 GbE?
  • 40 GbE?
  • 50 GbE?
  • 100 GbE?

From what I am reading it looks like 10 GbE is either an

- ethernet cable (a sturdy CAT6A cable & proper 10 GbE CAT6Aports)

or

- SFP+ ports with either fiber or copper cabling.

What about the rest of them though? Can we carry 25 GbE, 40 GbE, 50 GbE, 100 GbE on a copper CAT# cable or do we need to use #SFP#+ ports and fiber [or copper]?

NOTE: I believe my confusion came from thinking that ethernet means it has to be on a standard CAT# copper ethernet cable. I just remembered that ethernet is a layer2 data-link technology, so that means the layer1 physical (cat ports & copper cables, or #sfp#+ ports & copper or fibre cables) can be whatever supplies it.
