I worked, in the 1980s, at Citicorp's R&D center in California, during the transition from AT&Ts national microwave communications backbone to fiber optic. I analyzed our plans and pointed out the relative ease of disruption of the few cables, both dark and lit, routed along major highways by many miniature "guillotines" around the fibers remotely controlled by pagers.
