Abstract

We experimentally studied the performance of a delay-line interferometer-based optical signal-to-noise ratio (OSNR) monitor that is pre-calibrated in optimal conditions for 25-Gbaud pol-muxed quadrature-amplitudemodulation (QAM) signals, when unpredicted changes outside the monitor occurred either in the transmitter or the link.
