Polarization Mode Dispersion (PMD) : A form of dispersion in an optical fiber where two different polarization states of light travel at slight different velocities. This is caused by imperfections and asymmetries in the glass fiber core itself and results in random spreading of the optical signal.

EXFO's Be-an-Expert Program has produced the world's first animated glossary of fiber optic terms. Including concise definitions and animated sequences, this tool provides a great reference for anyone that wishes to understand fiber terminology.
