ABSTRACT:
Apparatus and methods for implementing a high-power or high-sensitivity tracking mode of operation in a free-space optical communication system are disclosed. Functions of the high-power or high-sensitivity tracking mode may be implemented in response to one or more engage signals generated and transmitted in response to a sensed inclement weather condition, such as fog or the like, which may interfere with communication of an optical signal between a pair of free-space optical terminals in the free-space optical communication system. Implementation of the high-power or high-sensitivity tracking mode facilitates maintenance of the alignment between the pair of free-space optical terminals throughout the duration of the inclement weather condition to allow data communication to resume fully after the inclement weather condition has diminished.
