LED Calculator Example

INPUTS:

  • Bandwidth-length product = 1000 MHz*Km
  • Length of fiber = 10 Km

OUTPUTS:

  • Optical Bandwidth = 100 MHz
  • Electrical Bandwidth = 70.7 MHz

Formula for Relation between Fiber Optical Bandwidth and Electrical Bandwidth

Electrical Bandwidth: Defined as the frequency at which the ratio of current output to current input drops to a value of 0.707.

Optical Bandwidth: Defined as the frequency at which the ratio of power output to power input drops to a value of 0.5.

The following equations are used for fiber optical bandwidth and electrical bandwidth calculations:
