Abstract
Optical cross connects and methods for use therewith are described herein. In an embodiment, an optical cross connect includes first and second mirror arrays, first and second light sources that respectively emit first and second color coded light beams (e.g., each of which includes red, green and blue light), and first and second cameras configured to respectively capture first and second color images of the first and second color coded light beams reflected respectively from the first and second mirror arrays. The optical cross connect also includes a controller configured to perform closed loop feedback control of the first and second mirror arrays, based on the first and second color images, when the controller controls how optical signals are transferred between individual optical fibers in a first bundle of optical fibers and individual optical fibers in a second bundle of optical fibers.
