If you get a chance to work with one of the "transparent" fibers (no signifigent jacket) you normally don't see any "leaks" along the way -- the fiber will appear "dark". However, if you create a too sharp bend, you will be able to see leaks at that point. You can also see this if you strip away some jacket on a regular fiber, then kink the exposed fiber. You'll be able to see leakage at the kink.

Every light path through some kind of medium has a critical angle and bending fiber optic is no different.

If you have a laser pointer or gun sight, aim it downward in a glass of water, then change the angle at the surface. It's interesting to see it change.
My mechanic told me, "I couldn't repair your brakes, so I made your horn louder."
