The answer is: Not really. Fiber optic communication, for all of its shortcomings, is actually pretty amazing, and it's getting better by the year. Accidents do happen. In 2006 earthquakes in the Luzon Strait near Taiwan severed seven of nine cables and wrought havoc on communications networks for weeks, and twice in 2008 cables in the Mediterranean were damaged, disrupting communications in the Middle East, Africa, and the Indian subcontinent (and that's just two recent examples--there are many, many more). But there's really no technology that can touch our current fiber optics technology. The solution to problems like those East Africa is currently experiencing is not less fiber optic cable, but more.
