Abstract
The present invention comprises an operational algorithm, and calibration process, for an avalanche photodiode (ADP) receiver which takes into account an APD behavioral model. In-situ optical and electrical measurements (calibration) of the APD are performed to determine key constants for use in the model. Knowledge of these constants allows for optimum operation of the APD over a wide range of input optical power. The operational algorithm also gives an estimate of input optical power over a wide range of ambient temperatures.
