| Zusammenfassung: | An optical fiber includes: a core; and a clad which is formed so as to surround an outer circumference of the core concentrically with the core, the clad having at least an inner cladding layer adjacent to the outer circumference of the core and an outer cladding layer formed on an outer circumference of the inner cladding layer, wherein a refractive index of the outer cladding layer is Δ3, and an outer circumference radius of the outer cladding layer is r3, a relationship of Δ1max>Δ3>Δ2min is satisfied, a relationship of Δ3−Δ2min≤0.08% is satisfied, a relationship of r1 |
