One, our own, is the tardyon-universe, in which all particles go at subluminal velocities and may accelerate to nearly the speed of light.

I've seen an automatic splicer (made by Northern Telecom I think) which injects light through the sheath in one fibre, and detects it through the sheath in a second piece. The fibres are held in a jig which puts a small kink in them at the point where the light is injected/detected. The equipment uses the light received to align the two parts before splicing. It's a pretty good indication of the hackability of fibre I would say.
