1. optical modulating circuit wherein, possesses:

  • The continuous light light source produces the fixing continuous light of power;

    The modulator driving signal generating unit, the data-modulated that should send is a modulator driving signal, wherein, this modulator driving signal produces optical sub-carrier, this optical sub-carrier have respectively in the front and back that are the center with described continuous light frequency the individual and l (l 〉

    =1) of m (m 〉

    =1) individual amount to l+m different frequency, and superimposed different pieces of information arranged;

    AndModulating sections uses described modulator driving signal to be modulated to described optical sub-carrier from the described continuous light of described continuous light light source.
