Fiber Length Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Fiber = Group Velocity*Group Delay
L = V_g*T_d
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 = V_g*T_d --> 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

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

Fiber Length Formula

Length of Fiber = Group Velocity*Group Delay
L = V_g*T_d

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.

FAQ

What is Fiber Length?

The Fiber Length formula is defined as the length of fiber cable that is being used to propagate the signal and is represented as L = V_g*T_d or Length of Fiber = Group Velocity*Group Delay. Group Velocity is the velocity with which the overall envelope shape of the wave's amplitudes; known as the modulation & Group delay is a measurement of the time taken by the modulated signal to get through the system.

How to calculate Fiber Length?

The Fiber Length formula is defined as the length of fiber cable that is being used to propagate the signal is calculated using Length of Fiber = Group Velocity*Group Delay. To calculate Fiber Length, you need Group Velocity (V_g) & Group Delay (T_d). With our tool, you need to enter the respective value for Group Velocity & Group Delay and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
