Publication number: 20240243540Abstract: 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 ±0.1 dB. While the model has good success predicting the performance of an EDFA it is trained with, it is not as successful when predicting a different EDFA, or the same EDFA with different pump power. Retraining the model with a small amount of supplementary data from a separate EDFA makes the model able to predict the performance of the second EDFA with little loss in performance. Experiments show that machine learning model of an EDFA is capable of modelling spectralhole burning effects accurately. As a result, it significantly outperforms black-box models that neglect inhomogenous effects. Model achieves an average RMSE error of 0.016 dB between the model and measurements.Type: ApplicationFiled: January 16, 2024Publication date: July 18, 2024Applicant: NEC Laboratories America, Inc.Inventors: Fatih YAMAN, Hussam BATSHON, Eduardo Fabian MATEO RODRIGUEZ, Yoshihisa INADA, Shinsuke FUJISAWA, Takanori INOUE

Publication number: 20240103215Abstract: An advance in the art is made according to aspects of the present disclosure directed to methods for earthquake sensing that employ a supervisory system of undersea fiber optic cables. Earthquakes and other environmental disturbances are detected by monitoring the polarization of interrogation light instead of its phase. More specifically, our methods monitor the transfer matrix rather than just polarization and isolate disturbance location by monitoring eigenvalues of the polarization transfer matrix. From results obtained we have demonstrated experimentally that we can monitor disturbances that affect signal polarization on a span-by-span basis using High Loss Loop Back (HLLB) paths. It is shown that by measuring the polarization rotation matrix and determining the polarization rotation angle we can identify the span where the disturbance occurred with 35 dB extinction with no limitation on the magnitude of the disturbance and the number of affected spans.Type: ApplicationFiled: September 15, 2023Publication date: March 28, 2024Applicants: NEC Laboratories America, Inc., NEC CorporationInventors: Fatih YAMAN, Shaobo HAN, Eduardo Fabian MATEO RODRIGUEZ, Yang LI, Yoshihisa INADA, Takanori INOUE

Patent number: 11933605Abstract: Aspects of the present disclosure describe estimating/measuring core-cladding concentricity error in optical fibers. In sharp contrast to the prior art, our inventive method is based on measuring a seemingly unrelated property of fibers called guided acoustic wave Brillouin scattering (GAWBS). As we shall show and describe, by analyzing this GAWBS property we advantageously determine what level of CCCE is exhibited by the optical fiber.Type: GrantFiled: January 17, 2022Date of Patent: March 19, 2024Assignee: NEC CorporationInventors: Fatih Yaman, Hussam Batshon, Shinsuke Fujisawa, Kohei Nakamura, Takanori Inoue, Eduardo Mateo Rodriguez, Yoshihisa Inada

Publication number: 20220381932Abstract: Earthquake detection via fiber sensing is provided using using a supervisory path of submarine cables wherein the supervisory system/path of a submarine optical cable conveys portion(s) of an optical signal back to an origin location periodically—i.e., at every repeater location. Advantageously, since it is known where a returning signal is coming from, a resolution equivalent to an undersea span length may be determined—which is sufficient for wide area disturbances such as earthquakes. The returned signal is sufficiently strong such that the signal-to-noise ratio of a returned/received signal is not limited by the ASE noise of the amplifiers. The returned signal is much larger as compared to a normal distributed acoustic sensing (DAS) return signal since the return signal according to aspects of the present disclosure is directed backward via an optical coupler/reflector/circulator having a much larger coupling ratio as compared to normal Rayleigh back scattering utilized in DAS.Type: ApplicationFiled: May 31, 2022Publication date: December 1, 2022Applicant: NEC LABORATORIES AMERICA, INCInventors: Fatih YAMAN, Yue-Kai HUANG, Ezra IP, Hussam BATSHON, Eduardo Mateo RODRIGUEZ, Kohei NAKAMURA, Takanori INOUE, Yoshihisa INADA

Patent number: 11467061Abstract: Aspects of the present disclosure describe a method for estimating mode field distribution in optical fibers from guided acoustic-wave Brillouin scattering wherein light for which the optical mode-field distribution is determined remains in the optical fibers and the distribution is made for light inside the fiber, and not at a fiber/air interface or other perturbation points to the fiber resulting in a more accurate representation of the optical mode-field distribution in the fiber. Since light is always in the fiber during the determination, no complicated fiber preparation steps or procedures are required and the mode-field distribution is determined as an average distribution along the length of the fiber under test.Type: GrantFiled: June 7, 2021Date of Patent: October 11, 2022Inventors: Fatih Yaman, Eduardo Mateo Rodriguez, Shinsuke Fujisawa, Hussam Batshon, Kohei Nakamura, Takanori Inoue, Yoshihisa Inada, Takaaki Ogata
