Untappable fiber?
If you know much about the physics of optical fiber, you know that there are ways to make light leak out without breaking the fiber.
That news is now widely known, since The Register has published an article about optical fiber eavesdropping with Exfo's FCD-10B coupler. I'm skeptical about the description of a "simple clip-on" device, given the amount of sheathing and armor on fiber lines, but Infoguard alleges that someone found an eavesdropping device on a Verizon fiber line in 2003.
Who's Infoguard? They sell encryption solutions for high-speed fiber.
