MULTIMODE OPTICAL FIBER AND SYSTEM INCORPORATING SUCH

摘要

According to some embodiments, a multimode optical fiber (100) comprises a graded index glass core (20) with refractive index ?1, a maximum refractive index delta ?1???, and a core radius between 10 and 40 microns; and cladding region (200) surrounding the core comprising refractive index ?4, wherein the fiber exhibits an overfilled bandwidth at an operating wavelength in a 900 to 1250 nm wave-length range of greater than 2.5 GHz-km. According to some embodiments the fiber exhibits an overfilled bandwidth at a wavelength be¬ tween 950 and 1100 nm which is greater than 4 GHz-km. According to some embodiments the fiber exhibits an overfilled bandwidth at a wavelength between 950 and 1100 nm which is greater than 10 GHz-km.
