Abstract: The present invention relates to an optical fiber (100) having a core region (102) and a cladding (104) defined by a relative refractive index profile (202). Particularly, the relative refractive index profile (202) varies from a center of the core region (102) to a periphery of the cladding (104). Moreover, the relative refractive index profile (202) has at least two low relative refractive index regions (208, 210) such that a relative refractive index at an interface (212, 218) of the at least two low relative refractive index regions (208, 210) is in a range between 0 and −0.1%.
