Result Interpretation

Optical Fiber Link Attenuation Budget Calculator computes Total Link Attenuation in dB using the defined engineering formula and the input values provided. Total Link Attenuation is expressed in dB. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Fiber Length = 20000
  • Fiber Attenuation Coefficient = 0.2
  • Number of Connectors = 4
  • Connector Loss per Unit = 0.25
  • Number of Splices = 3
  • Splice Loss per Unit = 0.08
  • System Margin = 2

Expected Result:

  • Total Link Attenuation = 4003.24

Engineering Interpretation:

Under the given input conditions, the calculated result is: Total Link Attenuation = 4003.24 dB.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method

total link attenuation = (fiber length * fiber attenuation coefficient) + (number of connectors * connector loss per unit) + (number of splices * splice loss per unit) + system margin
