International Journal of RF and Microwave Computer-Aided Engineering, Volume 2025, Issue 1, 2025.In this work, an artificial neural network (ANN) architecture is proposed to estimate the optical signal‐to‐noise ratio (OSNR) used in a dense wavelength‐division multiplexing (DWDM) transmission system in operational stations. The proposed neural network model, using the TensorFlow platform and Deep SHAP and kernel shape interpretation, provides a ...

IET Optoelectronics, Volume 18, Issue 6, Page 179-187, December 2024.Multicore (MC‐) erbium‐doped fibre amplifier (EDFA) architecture is classified from the viewpoint of the number of erbium‐doped fibre (EDF) cores and its pumping method. In particular, the advantages of cladding pumped MC‐EDFA are shown. Abstract Amplification technologies needed for spatial division multiplexing (SDM) signal transmission have been ...

IET Optoelectronics, Volume 18, Issue 5, Page 131-139, October 2024.1. The data‐free guided coherent reception DSP algorithm proposed based on spectral clustering can effectively suppress a variety of physical damage and increase the system’s OSNR tolerance. 2. When the bit error rate is 1.9E‐2, the spectral clustering‐based data‐agnostic DSP solution extends the maximum transmission distance of a 14GBaud PM‐16QAM ...
