Overfill
In telecommunication, the term overfill has the following meanings:
- The condition that prevails when the numerical aperture of an optical source , such as a laser, light-emitting diode, or optical fiber, exceeds that of the driven element, e.g., optical fiber core.
- The condition that prevails when the beam diameter of an optical source, such as a laser, light-emitting diode, or optical fiber, exceeds that of the driven element, e.g. optical fiber core.
Note: In optical communications testing, overfill in both numerical aperture and mean diameter (core diameter or spot size ) is usually required.
