## Fiber Optic Loss Calculator | Fiber Optic Loss Formula

This page covers Fiber Optic Loss calculator. It mentions formula used for this fiber optic loss calculator. The calculator-1 calculates loss based on input power,output power and length of fiber.

Input Power, µWatt (input1) :

Output Power, µWatt (input2) :

Fiber Length, Km (input3) :

Total Fiber Loss, dB (Output1):

Fiber Loss, dB/Km (Output2):

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

Following formula is used for calculator#1.

### Calculator-2

The calculator-2 calculates fiber output power based on fiber cable loss, length and input power.

Input Power, mWatt (input1) :

Fiber Loss in dB/Km (input2) :

Fiber Length, Km (input3) :

Output Power, mWatt (Output1):

Example calculator#2:
INPUTS : input power (mWatt) = 400 , Fiber Optic Loss (dB/Km) = 2.5 Length (Km) = 10
OUTPUTS: output power= 1.265 mWatt

### Formula for fiber optic output power calculator-2

Following formula is used for calculator#2.
