Abstract

An optical fiber, including (i) an inner core having an α-power refractive index profile, (ii) an outer core having a refractive index of n1′, and (iii) a cladding having a refractive index of n2 (n1′<n2<n1), is configured such that a depth of a trench, defined by n2−n1′, is sufficiently increased.
