I've never heard that they break the cables, but rather "bend" them so that light leaks out of the fibre.

It seems that'd be pretty easy to do that with, e.g., a few strands of SMF running across a datacenter, but I'd imagine it's a bit more difficult to "bend" a bundle of, say, 144 strands that are encased in a few inches of copper and steel, no?
