Calibration is the process of adjusting and fine-tuning the parameters of a device, instrument, or system to ensure its accuracy and precision in measuring or operating. This process involves comparing the measurements or outputs of the device to a known standard and making necessary adjustments to align them with the standard.
A differential algorithm is proposed to calibrate the physical digital model of an optical line system from scratch at the commissioning phase, using minimal measurements and maximizing signal and OSNR estimation accuracy.
A method is proposed in order to improve QoT-E by calibrating the physical model parameters of an optical link post-installation, using only total power monitors integrated into the EDFAs and an OSA at the receiver.
