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.
