基于传输常数的泰勒展开式，研究了光纤色散对双边带（DSB）、光载波抑制（OCS）和单边带（SSB）光毫米波信号的影响，并通过仿真进行了验证。根据我们的理论结果，衰落效应以类余弦模式周期性地抑制DSB光毫米波的信号功率，并且可以用传播常数的零阶泰勒展开来描述。对于信号调制在两个或多个音调上的光毫米波，毫米波信号的比特脉冲被音调之间的色散诱导比特走离效应所失真，该效应由传播常数的一阶泰勒展开表示。此外，随着信号速率和传输距离的进一步增加，即使完全消除衰落效应和比特走离效应，传播常数的高阶泰勒展开仍然使光学mm波信号劣化。基于传播常数的二阶泰勒展开，推导了单边带光毫米波信号脉冲的畸变。这种退化是通过模拟验证与SSB光毫米波信号的眼图演变。
The influence of the fiber chromatic dispersion on double sideband (DSB), optical carrier suppression (OCS), and single sideband (SSB) optical mm-wave signals is investigated based on the Taylor expansion of the propagation constant and is verified by simulation. According to our theoretical results, the fading effect suppresses the signal power of the DSB optical mm-wave periodically in a cosine-like pattern, and it can be described by the zero-order Taylor expansion of the propagation constant. For the optical mm-wave with the signal modulated on two or more tones, the bit pulses of the mm-wave signal are distorted by the dispersion-inducing bit walk-off effect between tones, which is expressed by the first-order Taylor expansion of the propagation constant. Moreover, as the signal rate and the transmission distance are increased further, higher-order Taylor expansion of the propagation constant still degrades the optical mm-wave signal even if both the fading effect and the bit walk-off effect are eliminated completely. The distortion of the signal pulses of SSB optical mm-wave is derived based on the second-order Taylor expansion of the propagation constant. This degradation is verified by the simulation with the eye diagram evolution of the SSB optical mm-wave signal.
