Fiber Optic Loss Calculator and Formula

This page provides information about a Fiber Optic Loss calculator and the formulas used in its calculations.

Calculator-1

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

Formula for Fiber Optic Loss Calculator-1

The following formula is used for Calculator #1:

Calculator-2

This calculator calculates the fiber output power based on the fiber cable loss (dB/Km), length of the cable, and the input power.

Example Calculator #2:

• INPUTS:
  • Input Power (mWatt) = 400
  • Fiber Optic Loss (dB/Km) = 2.5
  • Length (Km) = 10
• OUTPUTS:
  • Output Power = 1.265 mWatt
