| Term (EN) | profile dispersion parameter (symb.: P) |
|---|
| Definition (EN) | The quantity which characterizes that part of profile dispersion
P(λ)=(n_(1 ) λdΔ)/(N_1 Δdλ)
where n1 is the maximum refractive index of the core,
N1 is the group index corresponding to n1 calculated from the formula :
N1= n1 = λ(d n1 /d λ)
∆ is the refractive index contrast,
λ is the wavelength in vacuum.

P(λ)=(n_(1 ) λdΔ)/(N_1 Δdλ)
gdje je n1 maksimalni indeks prelamanja jezgre,
N1 je grupni indeks koji odgovara n1 izračunat na osnovu formule:
N1= n1 = λ(d n1 /d λ)
∆ je kontrast indeksa prelamanja,
λ je talasna dužina u vakuumu. |
