Power Loss in Fiber Solution

STEP 0: Pre-Calculation Summary

Formula Used

Power Loss Fiber = Input Power*exp(Attenuation Coefficient*Length of Fiber)
P_α = P_in*exp(α_p*L)
This formula uses 1 Functions, 4 Variables

Functions Used

exp - n an exponential function, the value of the function changes by a constant factor for every unit change in the independent variable., exp(Number)

Variables Used

Power Loss Fiber - (Measured in Watt) - Power Loss Fiber is attenuation loss in fiber.
Input Power - (Measured in Watt) - Input Power refers to the power of the signal at the beginning of fiber at time t=0.
Attenuation Coefficient - Attenuation coefficient is a measure of the rate at which an optical signal decreases in power as it propagates through an optical fiber.
Length of Fiber - (Measured in Meter) - Length of Fiber is defined as the total length of fiber cable.

STEP 1: Convert Input(s) to Base Unit

Input Power: 5.5 Watt --> 5.5 Watt No Conversion Required

Diameter of Fiber

Go Diameter of Fiber = (Wavelength of Light*Number of Modes)/(pi*Numerical Aperture)

Power Loss in Fiber

Go Power Loss Fiber = Input Power*exp(Attenuation Coefficient*Length of Fiber)

Fiber Attenuation Coefficient

Go Attenuation Coefficient = Attenuation Loss/4.343

Number of Modes using Normalized Frequency

Go Number of Modes = Normalized Frequency^2/2

Power Loss in Fiber Formula

Power Loss Fiber = Input Power*exp(Attenuation Coefficient*Length of Fiber)
P_α = P_in*exp(α_p*L)

Is the loss of power introduced by the fiber?

Optical fiber is a fantastic medium for propagating light signals, and it rarely needs amplification in contrast to copper cables. High-quality single mode fiber will often exhibit attenuation (loss of power) as low as 0.1dB per kilometer.

How to Calculate Power Loss in Fiber?

Power Loss in Fiber calculator uses Power Loss Fiber = Input Power*exp(Attenuation Coefficient*Length of Fiber) to calculate the Power Loss Fiber, Power Loss in Fiber formula refers to the reduction in the power of an optical signal as it propagates through an optical fiber at any particular length L, or it is the loss of power in light in an optical fiber is measured in decibels (dB). Power Loss Fiber is denoted by P_α symbol.

How to calculate Power Loss in Fiber using this online calculator? To use this online calculator for Power Loss in Fiber, enter Input Power (P_in), Attenuation Coefficient (α_p) & Length of Fiber (L) and hit the calculate button. Here is how the Power Loss in Fiber calculation can be explained with given input values -> 12.24048 = 5.5*exp(0.64*1.25).
