Bending What is Optical Fiber Dispersion?
... Since each mode ray travels a different distance as it propagates, the ray arrive at different times at the fiber output. So the light pulse spreads out in time which can cause signal overlapping so seriously that you cannot distinguish them any more.. ...

Light propagates in the form of waves

Electromagnetic radiation propagates in the form of two coupled vector waves, an electric-field wave and a magnetic-field wave. Although light is des ...
