| Term (EN) | core area |
| Definition (EN) | For a cross section of an optical fibre the area within which the refractive index everywhere (excluding any index dip) exceeds that of the innermost homogeneous cladding by a given fraction of the difference between the maximum of the refractive index of the core and the refractive index of the innermost homogenous cladding. Note. — The core area is the smallest cross-sectional area of a fibre excluding any index dip, which is contained within the locus of points where the refractive index n3 is given by : n3 = n2 + k (n1 — n2) where : n1 is maximum refractive index of the core, n2 is refractive index of the innermost homogeneous cladding, k is a constant (usually taken to be in the range 0 — 0.05). |

| Term (SR) | oblast jezgra |
| Definition (SR) | Za poprečni presjek optičkog vlakna, oblast u kojoj je indeks prelamanja svuda (isključujući bilo koji indeks propada) veći od najdubljeg homogenog omotača za dati iznos razlike između maksimalnog indeksa prelamanja jezgre i indeksa prelamanja najdubljeg homogenog omotača. Napomena — Oblast jezgre je najmanja površina poprečnog presjeka vlakna, isključujući bilo koji indeks propada), koji je sadržan unutar mjesta tačaka, gdje je indeks prelamanja n3 dat sa: n3 = n2 + k (n1 — n2) gdje je: n1 maksimalni indeks prelamanja jezgre, n2 indeks prelamanja najdubljeg homogenog omotača, k konstanta (obično uzeta iz opsega 0 - 0,05). |
