摘要: Utility data modulation is superimposed on a payload modulator optical signal by exploiting spread spectrum techniques virtue of one embodiment the present invention. transmission rates e.g., 200 Kbps, can be achieved without impairment to transmission. The utility modulated overlaps or entirely within spectrum, therefore, overcoming problems with amplifier gain control and pink noise.
