Fiber Optical Bandwidth and Electrical Bandwidth Calculator

This page covers the fiber optical bandwidth and electrical bandwidth calculator, including their formulas. It also explains the relationship between optical bandwidth and electrical bandwidth.

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:

The relationship between optical bandwidth and electrical bandwidth can be expressed with a formula (not explicitly provided in the original text, but implied):

Note: The original text does not provide the explicit formula linking Optical Bandwidth and Electrical Bandwidth, so this section is left as a placeholder for future expansion if the formula becomes available.
