我们从理论上研究了利用马赫-曾德尔调制器强度调制产生的光毫米波在双边带和单边带以及光载波抑制方案下的传输性能。根据理论分析，光纤色散会导致码的衰落效应和时移，从而使信号严重恶化。在所有的信号中，DSB光毫米波信号同时受到衰落效应和码时移的影响。然而，由SSB和OCS方案产生的光毫米波不受衰落效应的影响，而码的时移限制了它们的传输距离。实验和仿真结果证实了理论分析的正确性。
We have theoretically investigated the transmission performance of the optical millimeter-waves (mm-waves) generated using intensity modulation via a Mach-Zehnder modulator, with the double and single sidebands (DSB and SSB) and optical carrier suppression (OCS) schemes. According to our theoretical analysis, fiber chromatic dispersion leads to fading effect and time shifting of the codes; therefore, signals are greatly degraded. Of all signals, DSB optical mm-wave suffers from both the fading effect and the time shifting of the codes. However, the optical mm-waves generated by SSB and OCS schemes are immune to the fading effect, while the time shifting of the codes limits their transmission distance. Experimental and simulation results confirm the theoretical analysis.
