Polarisation Mode Dispersion (PMD)
Polarisation Mode Dispersion(PMD) results from the two polarisation states experiencing different effective refractive indexes (Birefringence) that vary randomly along the fibers length.
There are various technologies available to measure PMD and each technology lends itself to a particular application for the measurement. What works well on a a fiber that has relatively high PMD, will not necessarily cope quite so well when the PMD is relatively low and vice-versa. For this reason, PE.fiberoptics has developed a range of solutions that address the specific needs of each application. The option to measure by one or other of the various standards enables the user to choose the most suitable instrument for the application.
The 'Production/Lab' range is suitable for manufacturers of fiber and cables.
The 'Field Equipment' range is suitable for measuring installed links in the field.
