Which of the following statements is true about chromatic dispersion (CD)?

Question

Bobby Pick · Accepted Answer

Different wavelengths propagate at different speeds within the same media and therefore different colors travel in the fiber with different speed.

Bobby Pick · Answer

Different channels have different bandwidth and this causes different CD performances.

Bobby Pick · Answer

The fiber attenuation changes along the fiber, and when the light crosses these differences the CD takes place.

Bobby Pick · Answer

The fiber attenuation introduces inter-channel interference.
