even in the 1970s and 80's all they had to do was park a box next to cable and monitor it via induction no cutting needed

Tha article said this is affecting fiber cables and fiber can not be read by induction. For induction to work you need a magnetic field and that means electricity which means copper.

 True, however I seem to recall hearing of a case where a U.S. sub intercepted a soviet fiber cable. They didn't cut it, they cut open the sheath, and bent the fibers slightly. Enough to cause light leakage through the fiber wall that could be detected by their equipment to intercept traffic, but not enough to cause detectable degradation by the cable terminal equipment.

You don't need to cut into a figer cable and they are not using "induction". induction implies and requires a magnetic field, well for the most part it does. There is the technology to read fiber in a method similar to "induction" in that you don't need to cut the cable, and now you don't even need to cut the cable housing. You can park a box next to the fiber or on a cable crawler and "read" the fiber outside the sheath.
