Dispersion in optical fibers limits the quality of signal transmission. Both CD and PMD must be measured to assess the potential of upgrading networks to higher transmission speeds, or to evaluate the need for compensations. Various testing solutions exist, each having advantages and drawbacks. As an aid to finding the most appropriate solution, this paper described the causes and effects of CD and PMD in optical networks and the details of the various testing methods.
