  1. light carries less information over fiber than RF can over coax
  2. light is unaffected by interference from lightning or other electrical sources, whereas RF is highly susceptible to these factors
  3. light causes interference with other signals within the cable, but RF does not.
  4. light frequencies are measured to hertz, but radio frequencies are measured in wavelengths.
