    摘要： The present invention relates generally to multimode optical fibers (MMFs) and methods for optimizing said MMFs for transmission for at least two optical wavelengths. In an embodiment, the present invention is a multimode optical fiber optimized for multi-wavelength transmission in communication systems utilizing VCSEL transceivers, where the MMF has a bandwidth designed to maximize and equalize channel reach for multiple wavelengths, and/or where the MMF minimizes for wavelength dependent optical power penalties at one or more wavelengths. The alpha coefficient of the refractive index profile is numerically optimized for all wavelengths based on a transmission model that includes calculation of, inter alia, modal dispersion and chromatic dispersion effects.

    摘要： A method of manufacturing a graded-index multimode optical fiber having at least one dopant. The graded-index multimode optical fiber comprising a core, the core having a center, a radius R, and a refractive index profile; and a cladding surrounding the core. The method comprising the steps of: selecting the at least one dopant; introducing the at least one dopant into the core; and controlling the concentration of the at least one dopant during the introduction to produce the refractive index profile, the at least one dopant being selected and the concentration of the at least one dopant being controlled such that the refractive index profile causes the graded-index multimode optical fiber to exacerbate modal chromatic dispersion interaction when coupled with an optical transmitter, the at least one dopant being further selected and the concentration of the at least one dopant being further controlled such that an effective modal bandwidth (EMB) of the graded-index multimode optical fiber is equal to a minimum modal bandwidth requirement specified by a defined standard +/- 10%.
