Claim:
1. A system comprising: a detector array having a plurality of level detectors to monitor an optical input signal, wherein each level detector of the detector array operates in a different operating range, each operating range for each level detector having a different saturation level and a different cutoff level based on a power level of the optical input signal; a first level detector of the plurality of level detectors having a first operating range and operating at cutoff in response to the optical input signal; a second level detector of the plurality of level detectors having a second operating range and operating at saturation in response to the optical input signal; a third level detector of the plurality of level detectors operating at a third level between the first level and the second level, the third level being associated with a present power level of the optical input signal; and a controller to monitor each level detector of the plurality of level detectors to detect the present power level for the optical input signal, and to dynamically adjust the sensitivity level of a receiver photodetector in response to the detected present power level.
