Fiber Length Solution

STEP 0: Pre-Calculation Summary
Formula Used
Length of Fiber = Group Velocity*Group Delay
L = Vg*Td
This formula uses 3 Variables
Variables Used
Length of Fiber - (Measured in Meter) - Length of Fiber is defined as the total length of fiber cable.
Group Velocity - (Measured in Meter per Second) - Group Velocity is the velocity with which the overall envelope shape of the wave's amplitudes; known as the modulation.
Group Delay - (Measured in Second) - Group delay is a measurement of the time taken by the modulated signal to get through the system.
STEP 1: Convert Input(s) to Base Unit
Group Velocity: 250000000 Meter per Second --> 250000000 Meter per Second No Conversion Required
Group Delay: 5E-09 Second --> 5E-09 Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
L = Vg*Td --> 250000000*5E-09
Evaluating ... ...
L = 1.25
STEP 3: Convert Result to Output's Unit
1.25 Meter --> No Conversion Required
FINAL ANSWER
1.25 Meter <-- Length of Fiber
(Calculation completed in 00.004 seconds)

Effective Interaction Length
Go Effective Interaction Length = (1-exp(-(Attenuation Loss*Length of Fiber)))/Attenuation Loss
Optical Dispersion
Go Optical Fiber Dispersion = (2*pi*[c]*Propagation Constant)/Wavelength of Light^2
Diameter of Fiber
Go Diameter of Fiber = (Wavelength of Light*Number of Modes)/(pi*Numerical Aperture)
Number of Modes
Go Number of Modes = (2*pi*Radius of Core*Numerical Aperture)/Wavelength of Light
Power Loss in Fiber
Go Power Loss Fiber = Input Power*exp(Attenuation Coefficient*Length of Fiber)
Gaussian Pulse
Go Gaussian Pulse = Optical Pulse Duration/(Length of Fiber*Optical Fiber Dispersion)
Brillouin Shift
Go Brillouin shift = (2*Mode Index*Acoustic Velocity)/Pump Wavelength
Modal Birefringence Degree
Go Modal Birefringence Degree = modulus(Mode Index X-Mode Index Y)
Rayleigh Scattering
Go Rayleigh Scattering = Fiber Constant/(Wavelength of Light^4)
Beat Length

What is fiber staple length?

What is fiber staple length?
Image result for Fiber Length
Long staple fibres have a length of more than 60 mm. Wool fibres are long staples, with a length of about 60–150 mm. As a result of their short length and non-uniform nature, staple fibres require greater processing before a satisfactory yarn can be produced; this obviously adds to production costs.

How to Calculate Fiber Length?

Fiber Length calculator uses Length of Fiber = Group Velocity*Group Delay to calculate the Length of Fiber, The Fiber Length formula is defined as the length of fiber cable that is being used to propagate the signal. Length of Fiber is denoted by L symbol.
