Optical Fiber Networks are systems that use optical fibers to transmit data such as light signals over long distances. These networks form the backbone of modern telecommunications and internet infrastructure, providing high-speed, high-capacity data transfer essential for a wide range of applications, from everyday internet use to specialized industrial and medical systems.
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.
