Chromatic Dispersion in Fiber Networks

Optical dispersion is the spreading of an optical pulse as it travels along a fiber. The effects of dispersion accumulate with distance, and can limit how far a signal can be transmitted through a fiber without affecting signal quality. Once the spreading of the pulses starts to overlap, the signal quality decreases. Designers must consider the effects of optical dispersion when upgrading to higher speeds or longer distances.
