Novel OSNR Measurement Techniques for Coherent-Detection Systems

Optical Fiber Communication Conference, 2018
We discuss in-service OSNR measurement options independent of coherent receiver metrics. We review a spectral analysis technique for discriminating ASE when fiber nonlinearities contribute “Gaussian-like” noise and evaluate its performance in practical network scenarios.

BER and OSNR Based Quality Estimation in Optical Networks using Machine Learning Algorithms

2023 2nd International Conference on Vision Towards Emerging Trends in Communication and Networking Technologies (ViTECoN), 2023
Currently, optical fiber technology has become much more advanced to transmit higher data rates over long-distance transmissions. In this area, the research and development work is growing first. The physical layer impairments are an essential estimation

Modeling Transceiver BER-OSNR Characteristic for QoT Estimation in Short-Reach Systems

International Conference on Optical Network Design and Modelling, 2023
A transceiver BER-OSNR model is validated and applied the Q-factor estimation for short-reach systems. Experiments using pluggable transceivers with commercial DSPs show that the modeling and estimation errors are less than 0.05 dB and 0.15 dB ...

OSNR-Aware Digital Pre-Emphasis for High Baudrate Coherent Optical Transmissions

Optical Fiber Communications Conference and Exhibition, 2022
We derive and experimentally verify an analytical expression for adaptive digital pre-emphasis in coherent optical transmission systems with severe bandwidth limitation by considering both the transmitter response and optical link OSNR.
