3. Fiber Height (nm) – yes Displays the amount of undercut or protrusion of the fiber in the connector. The
CC6000 software determines the Spherical Fiber Height, which is defined as the difference in the height
between the center of the fiber and the theoretical height in the center based on the ferrule. This is the
method recommended in the TIA and IEC test procedures.
The TIA use a sliding scale for the amount of undercut recommended as a function of the Radius of
Curvature. The formula below shows this relationship.
• Sign Convention for Fiber Height:
o + = Protrusion
o - = Undercut
Where is Fiber Undercut and is Radius of Curvature
