Calculator-1

Inputs

Outputs

This calculator determines fiber loss based on input power, output power, and the length of the fiber optic cable.

Example Calculator #1:

  • INPUTS:
    • Input Power (µW) = 10
    • Output Power (µW) = 9
    • Length of Fiber (Km) = 0.5
  • OUTPUTS:
    • Fiber Optic Loss (dB) = -0.458
    • Loss (dB/Km) = -0.915
