In telecommunications and fiber optics, ovality or noncircularity is the degree of deviation from perfect circularity of the cross section of the core or cladding of the fiber.
The cross-sections of the core and cladding are assumed to a first approximation to be elliptical, and ovality is defined to be twice the third flattening of the ellipse, , where a is the length of the major axis and b is the length of the minor axis. This dimensionless quantity is between 0 and 1, and may be multiplied by 100 to express ovality as a percentage. Alternatively, ovality of the core or cladding may be specified by a tolerance field consisting of two concentric circles, within which the cross section boundaries must lie.
In measurements, ovality is the amount of out-of-roundness of a hole or cylindrical part in the typical form of an oval.
