Hi,
I'm having trouble calculating the normalized frequency for a multimode fiber. Here's the formula:
V=(2π/λ)⋅a⋅√(n12-n22)
where λ=900 nm, a=200μm, n1=1.460, n2=1.455
Here's how I plug in the numbers:
V=(2π/(900*10-9))⋅(200*10-6)⋅√(1.4602-1.4552)=167This is an easy calculation I know that, but I get the wrong answer. It's supposed to be 84 but I get 167 which is obviously far away from the real answer. I don't understand what I do wrong?
