Error function analysis of optical components
View Patent ↗A device and method that performs error analysis of an optical component. An optical transmitter transmits a test signal at a plurality of selected optical power levels. A port outputs the test signal to the optical component, and then receives a version of the test signal from the optical component. A receiver determines errors in the received version of the test signal. A processor determines an error rate at each of the selected optical power levels based on the determined errors, and also determines an uncertainty range for each determined error rate. An interface provides indication of the determined error rates in relation to the determined uncertainty ranges.
