Optical millimeter-wave signal generation using Stimulated Brillouin Scattering (SBS) is proposed in this work. The performance of generated signal is compared based on different external modulation scheme which are Single-Sideband (SSB) and Double-Sideband (DSB). Dispersion and the fading effect are the main cause for external modulation scheme system performance degrading while producing high Bit Error Rate (BER) when involving long distance delivery in the optical signal. According to simulation results, SBS technique successfully improve the system performance in terms of highest received signal over distance, the lowest bit error rate and coherence input power. The analysis of BER curve and plotting of eye diagram is evaluated to measure the differences of each method performance system.
