ABSTRACT:
A system, method, and computer readable medium for measurement of burst mode optical power over multiple bursts, comprises mirroring a photodiode current of an optical signal burst, converting the mirrored photodiode current to a capacitor voltage, comparing the capacitor voltage to a pre-determined threshold voltage, and accumulating a burst time necessary for the capacitor voltage to reach the pre-determined threshold voltage.
