Abstract
A method for automated calibration of an avalanche photodiode receiver includes measuring two values of avalanche photodiode biases at two successive times, measuring and comparing a bit error rate corresponding to each value. When the bit error rate of the second value is equal to or greater than the bit error rate of the first value, then a third value and a fourth value of avalanche photodiode bias closer together are measured. When the bit error rate of the fourth value is smaller than the bit error rate of the third value, two subsequent values as third value and fourth value are measured, and an optimum avalanche photodiode bias when the bit error rate of the fourth value is equal to the bit error rate of the third value is measured.
