    You laugh, but I once had a Future Shop employee try to sell me an expensive toslink cable by saying it had electromagnetic shielding. I replied that it’s light, for him to say that emp affect light. I laughed in his face, leaving with the cheap one.

      Even if it does affect light (which I’m not actually sure about since light is EMR) it’s irrelevant because the signal is digital. It only matters whether a 0 or 1 can be interpreted on the other end, which a bit of wiggle won’t change.
