Abstract
One embodiment of the disclosure relates to a few moded optical fiber comprises: a glass graded index core having alpha profile such that 2.0≦α≦2.15, a diameter Din the range of 13 microns to 40 microns, a maximum relative refractive index between 0.265 and 0.65 percent, core being structured to propagate more with X number of mode groups at a wavelength of 850 nm, wherein X is an integer greater than 1 and less than 8; and (b) a cladding including a depressed-index annular region surrounding the inner cladding. The fiber has an overfilled bandwidth greater than 2.0 GHz-km at 850 nm and relative microbending sensitivity γ such that γ≦1.5.
