Transmission performance of the optical mm-wave generated by double-sideband intensity-modulation

We have theoretically investigated the transmission of the optical mm-wave generated by the double-sideband (DSB) intensity-modulation. According to our analysis and simulation, the data signals, carried by DSB optical mm-wave after transmission along fiber, are degraded greatly because of the fading effect and the time shift of the codes caused by the chromatic dispersion in fiber, and these effects limit the transmission distance of the signals. Our theory is confirmed by the experimental results.
