Glimmerglass Intercepts Undersea Cable Traffic for Spy Agencies?

that is, if they even bother to install it on the cable itself and don't just force the endpoints to have their black boxes installed.

tapping a fibre isn't easy, you need a special submarine for that. the U.S. did that in the 1970s to the soviets. but it is much easier if the companies give you direct access at the landing station, which appears to be the case for the NSA
There are both secret- and top-secret-level clearances for civilians, and are usually dealt with in conjunction to companies and labs providing products and services dealing with state secrets.
And what's to stop multiple countries tapping the same fibre?
The biggest thing stopping multiple countries from tapping the same fibers is signal strength; I imagine that it becomes obvious that you've got a 'leak' after just a few splices. The other thing is that few countries posess the technology to pull off an undersea cable tap; There's only one USS Jimmy Carter, and I don't think the US loans it out, and while I'm certain that China, Russia, and some of the major European states have their equivalents, I doubt the list is very long.
None of this matters in context of the article, of course; Glimmerglass's technology seems to mostly live on the ends of these cables, in the comms cabinets just onshore where the cables emerge. There, you can tap as much as you want, so long as you're the sovereign. They simply wave a national security letter or equivalent in the face of the telco, and they've got a rack next to the cables doing whatever it is they want to do.

On the other hand, it's forgivable -- based on the plain meaning of the word "mining", it's often a better fit than the "predictive modeling/machine learning" meanings the term actually has.
