I.O.R.
(index of refraction)
The index of refraction is the ratio of the speed of light in a
vacuum to the speed of light in a fiber. The troubleshooter uses
the index of refraction to calculate length. If you increase n, the
calculated length decreases. The default is 1.468. This value is
satisfactory for most fibers.
