For those wanting a bit of a summary.
The breakthrough isn’t things moving faster but more fibers per cable. So you can transfer more bits in parallel.
That’s still a good breakthrough because, for lots of reasons, packing more fibers in isn’t as straight forward as one would think.
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
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
