profile dispersion

Profile dispersion is a dispersion that is due to production tolerances in the manufacture of optical fibers.

Particularly in the case of gradient fiber, 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 distortions caused by this are called intramodal distortions.
