What is intermodal dispersion?

Intermodal dispersion refers to the phenomenon where different modes of light (such as different wavelengths or frequencies) travel at different speeds through a medium, leading to a spreading of the light pulse over time. This effect is particularly significant in optical fibers, where it can cause distortion in signals as multiple light modes arrive at different times. The dispersion can affect data transmission rates and overall signal integrity in communication systems. Managing intermodal dispersion is crucial for optimizing the performance of fiber optic networks.
