Latest Patents
Hagimoto holds 2 patents, with his latest inventions focusing on an optical regenerator and an optical transmission system. The optical regenerator features a first clock extraction device that recovers a receiving clock, which follows the jitter present in a receiving optical signal caused by fiber wavelength dispersion. This innovation allows the receiving optical signal to be detected in synchrony with the receiving clock. The transmission section includes a transmitter that generates a transmission optical signal, altered in phase to suppress stimulated Brillouin scattering, along with a second clock extraction device that regenerates the transmission clock without following the jitter. The data from the receiving optical signal is processed at a processing unit and intensity-modulated based on the processed data, with modulation timing synchronized to the transmission clock. This design ensures that the receiving clock is synchronized with the jitter, preventing logic errors, while the transmission clock does not follow the jitter, thus avoiding its accumulation.
