Abstract:
    A method for modulating light counter mark based on offset quadrature of residual sideband includes expanding input light pulse to be wider by residual sideband filter for making time domain pulse form be move smooth before input signal light is modulated, dividing input light to two portions by beam splitter after said signal light is entered into input end, passing one portion through polarizer and using error code tester to receive light countermark signal, restoring another portion to be offset state by countermark eraser then sending it into the second error code tester to receive light load signal.
