Dispersion in Fibres

Product picture



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 tofinding 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.




This paper presents the causes and effects of dispersion and describes the different ways to measure it.
