Example Values:
- INPUTS: V-number = 2.405, λ = 1550 nm, NA = 0.12
- OUTPUTS: 9.888 µm
Single Mode Fiber Diameter Formula
The following formula is used for the single mode fiber diameter calculation:
Where:
d= Core Diameterλ= WavelengthV= Normalized Frequency (V-number)NA= Numerical Aperture
Here, V is the normalized frequency or V-number.
