No, it's actually more cores per fiber, and using those very well for space division multiplexing on top of the normal wavelength division multiplexing. They are talking about 22.9 Pb/s per fiber, not cable, the Tom's Hardware article is just wrong.
Cables can already contain hundreds of fibers, for example 576 here or into the thousands if you use stacks of ribbon cables in the subunits, for example 3456 here
Here's a source that backs up what you're talking about and proving that the TomsHardware article is wrong: https://www.nict.go.jp/en/press/2023/11/30-1.html
Thank you!
Yes, thanks to all for contributing and assisting. I am grateful for the clarification and leg work. Folks say reddit had this, and lemmy has less, so every time I see it, I make sure to appreciate it.
Am I to understand that the cable use has multiple cores within a single cladding? Interesting approach..
Now we get to classify them as singlemode, multimode, and multiestmode.
Yeah. Check this comment
This is really interesting. Thank you for providing good insight!
