Abstract:
1. A method of manufacturing an improved multimode optical fiber for use with an optical source having a spatially dependent wavelength emission pattern, the fiber comprising: a cladding; and a core including a center, a maximum radius, and radial offsets being measured from the center, the core further including a refractive index profile, the method comprising the steps of: generating an optical signal into a first end of a reference multimode fiber optic cable; measuring a time of flight for the optical signal at a second end of the reference multimode fiber optic cable; using the measured time of flight to determine an amount of chromatic dispersion and an amount of modal dispersion present in the reference multimode fiber cable; and manufacturing the improved multimode optical fiber wherein the refractive index profile is designed to compensate for at least a portion of the chromatic dispersion and modal dispersion present in the reference multimode fiber optic cable.
