Abstract:
We demonstrate a robust, accurate, and wide-range frequency-dependent crosstalk calibration method for coherent optical transceivers. Without any additional instrument, the calibration error is within 2dB under 20dB crosstalk ripple-fluctuation, and the calibration range can reach -40dB to -5dB which is the maximum reported so far.
