For those wanting a bit of a summary.

transmitting up to 22.9 petabits per second (Pb/s) through a single optic cable composed of multiple fibers

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.
