  • Publication number: 20250202591
    Abstract: An aim is to provide an optical communication system and an optical communication method for transmitting a wavelength-multiplexed signal whose signal quality on a reception side is adjusted to desired quality. A first optical transmitter outputs a first optical signal of a first wavelength at a first transmission intensity. A second optical transmitter outputs a second optical signal of a second wavelength longer than the first wavelength at a second transmission intensity lower than the first transmission intensity. A multiplexer outputs a third optical signal obtained by multiplexing the first optical signal and the second optical signal to an optical transmission line. The intensity of the first optical signal transmitted through the optical transmission line is reduced by inter-signal stimulated Raman scattering. The second optical signal transmitted through the optical transmission line is amplified by the inter-signal stimulated Raman scattering of the first optical signal.

  • Patent number: 12333005
    Abstract: A method for implementing a self-attentive encoder-decoder transformer framework for anomaly detection in event sequences is presented. The method includes feeding event content information into a content-awareness layer to generate event representations, inputting, into an encoder, event sequences of two hierarchies to capture long-term and short-term patterns and to generate feature maps, adding, in the decoder, a special sequence token at a beginning of an input sequence under detection, during a training stage, applying a one-class objective to bound the decoded special sequence token with a reconstruction loss for sequence forecasting using the generated feature maps from the encoder, and during a testing stage, labeling any event representation whose decoded special sequence token lies outside a hypersphere as an anomaly.

  • Patent number: 12332394
    Abstract: 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.

  • Patent number: 12333620
    Abstract: An operation control apparatus (10) includes a data acquisition unit (110) and an apparatus control unit (120). The data acquisition unit (110) acquires first congestion data. In a present example, the data acquisition unit (110) generates the first congestion data by processing an image generated by an image capture unit. The image processing performed herein includes, for example, processing of counting the number of persons in a crowd. The apparatus control unit (120) controls an apparatus to be controlled by using the first congestion data. For example, when the first congestion data exceed a reference value, the apparatus control unit (120) reduces the number of operating apparatuses to be controlled and lowers a response speed of the apparatus to be controlled in such a way that the number of persons moving from a second area to a first area per unit time decreases.
