profile dispersion

The profile dispersion is a dispersion that is due to production tolerances in the manufacture of optical

fibers. Especially with gradient fibers, the refraction profile must be homogeneous across the fiber cross-section. The smallest deviations cause different refractions, resulting in propagation time differences, which are referred to as profile dispersion. The resulting distortions are called intramodal distortions.
