Following are the limitations:

  • Coupling losses are high for LED
  • Radiant output power for a LED is less so it can be used for short distances.
  • LED’s supports less bit rates (few hundred of mbps) as switching speed is slow.
  • LED has wide spectral width hence chromatic dispersion loss is present.
