Abstract

An optical fiber for wavelength division multiplexing (WDM) communications, includes: an inner core having a predetermined refractive index, formed to a first predetermined radius from a central axis of the optical fiber, an outer core having a refractive index which is lower than the refractive index of the inner core and gets linearly smaller from its inner side to its outer side, formed on an outer side of the inner core to have a second predetermined radius, and a cladding formed on an outer side of the outer core to have a third predetermined radius.
