US Patent Issued to NEC on Sept. 8 for "Data-driven modeling of erbium doped fiber amplifiers by neural networks" (Japanese, American Inventors)

ALEXANDRIA, Va., Sept. 8 -- United States Patent no. 12,731,952, issued on Sept. 8, was assigned to NEC Corp. (Tokyo).

"Data-driven modeling of erbium doped fiber amplifiers by neural networks" was invented by Fatih Yaman (Princeton, N.J.), Hussam Batshon (Monroe, N.J.), Eduardo Fabian Mateo Rodriguez (Tokyo), Yoshihisa Inada (Tokyo), Shinsuke Fujisawa (Tokyo) and Takanori Inoue (Tokyo).

According to the abstract* released by the U.S. Patent & Trademark Office: "Dependence of EDFA gain shape on input power and input spectrum shape is modelled using a simple neural network-based architecture for amplifiers with different gains and output powers. The model can predict the gain within plus-minus0.1 dB. While the model has good success predic...
