"computes while data in transit over optical fibers... speed: tera- to peta-scale operations/ second, energy consumption: femtojoules to attojoules/ operation, latency: pico- to nanoseconds... remote access to optical processor without digital conversion drastically reduces computing latency... performs machine learning computations within optical fiber... proof-of-concept combining computation with data transfer over 20 km fiber access line achieved good classification accuracy for image recognition tasks"
