Ah, I see now. Problems in fibre optic communications over long idsstances is dispersion of light when light pulses start interferring with each other becuase of dispersive media.
I know of another place it would be useful, in optical memory. There's some interesting research in easily manipulating wavelength to store memory in light, trapping it in between mirror or something like that.
