Abstract
A method of manufacturing a multimode optical fiber includes specifying a peak wavelength λfor the multimode optical fiber. The peak wavelength λcorresponds to a wavelength at which the multimode optical fiber has a maximum bandwidth. The multimode optical fiber comprises a core and a cladding surrounding and directly adjacent to the core. The core has a radius rand a maximum relative refractive index Δ>0. The cladding comprises a depressed-index region having a minimum relative refractive index Δ<0 and a volume v. A draw tension T for the multimode optical fiber is selected based on a correlation relating peak wavelength λto draw tension T, the correlation comprising a correlation constant. The correlation constant K is a function of at least one of Δ, r, v, Δ, and λ. The multimode optical fiber is drawn from a preform at the draw tension T.
