Abstract
An optical cross connect switch includes a number of monitor channels. The monitor channels can be used to calibrate the switch while it is in operation. The coordinates associated with individual channels of the switching unit may be represented in a common coordinate system. Transformations between the common coordinate system and coordinate systems of individual channels may be adjusted to compensate for drift.
