Q

CHROMATIC DISPERSION

A

A RESULT OF THE PHENOMENON THAT THE VELOCITY OF PROPOGATION IN A MEDIUM IS FREQUENCY DEPENDENT, WHICH CAUSES THE FREQUENCY COMPONENTS TO LOSE PHASE COHERENCE AS IT PROPOGATES (E.G, TRANSMITTED PULSE WILL SPREAD OUT AS IT PROPOGATES.

Q

MODAL DISPERSION

A

A CHARACTERISTIC OF TRANSMISSION IN AN OPTICAL FIBER THAT RESULTS FROM DIFFERENT LENGTHS OF THE LIGHT PATHS TAKEN BY THE MANY MODES OF LIGHT AS THEY TRAVEL DOWN THE FIBER FROM SOURCE TO RECEIVER. ALSO CALLED MODAL DISTORTION.
