Explain the significance of V number.
Ans:
V number or V parameter or normalized cutoff frequency is one of the parameter which is used to calculate the maximum number of modes passing through the fiber.
The V number is defined as:
V= Πd (n12- n22)½ / λ
= 2Πa NA / λ
From this equation it is clear that the V number depends upon
From the calculation of V number we can easily calculate the number of modes passing through the fiber.
For a step index fiber, the number modes is given by
Number modes = V2/2
Where V >20
For a graded index fiber
Number modes = [y/(y+2)] V2/2
Where y is the index profile
The value of y =1 (for a triangular profile)
y=2 (for parabolic profile)
in commonly used case number of modes = V2/4
