eccentricity
- Eccentricity is an axis misalignment occurring in FO connectors, which leads to undesired attenuation of the infrared radiation guided in the optical fiber and has its cause in a lack of mechanical precision.
- The term eccentricity is also used for coaxial cables. It is the deviation of the inner conductor from the geometrical center of the dielectric. The deviation is expressed as a percentage of the radius of the dielectric.
- For compact disc( CD), eccentricity is the deviation of the distance from the center of the compact disc to the mean distance of the track spiral.
- For navigation satellites, the eccentricity is the ratio of the distances between the center of each ellipse and the two focal points on the principal axes.
