CONCENTRICITY ERROR

In an optical fiber , the distance between the center of the two concentric circles that specify the cladding diameter and the center of the two concentric circles that specify the core diameter . Note: The concentricity error is used in conjunction with tolerance fields to specify or characterize optical fiber core and cladding geometry. Synonyms core eccentricity, core-to-cladding concentricity, core-to-cladding eccentricity, core-to-cladding offset.
