Abstract
An optical cross connect with simultaneous correction of multiple mirror angles to achieve desired output power. In one embodiment beam offset and pointing angle are changed and output power is measured to determine changes to mirror angles.
Claims30
A process of coupling inputs and outputs in an optical cross connect, a particular input and a particular output being coupled by a first mirror moveable in azimuth and elevation and a second mirror moveable in azimuth and elevation, the process comprising:
- selecting a desired output beam power;
- traversing a number of points by a beam provided by the particular input by changing the azimuth and elevation of the first and second mirrors;
- measuring output power provided to the particular output;
- comparing the measured output power to the desired output power;
- and
- adjusting changes in the azimuth and elevation of the first and second mirrors based on the measured output power.
