Abstract

One exemplary multimode optical fiber includes a graded index glass core having a diameter in the range of 41 microns to 80 microns , a graded index having an alpha less than 2.04 and a maximum relative refractive index in the range between 0.6% and 1.8%. The cladding includes a depressed- index annular portion. The fiber has an overfilled bandwidth greater than 2.5 GHz -km at at least one wavelength between 1200 nm and 1700 nm.
