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： The present invention generally relates to the field of fiber optics, and more particularly, to apparatuses, systems, and methods directed towards improving effective modal bandwidth within a fiber optic communication environment. In an embodiment, a multimode optical fiber in accordance with the present invention comprises a core and cladding material system where the refractive indices of the core and cladding are selected to modify the shape of the profile dispersion parameter, y, as a function of wavelength in such a way that the alpha parameter (α-parameter), which defines the refractive index profile, produces negative relative group delays over a broad range of wavelengths. The new shape of the profile dispersion parameter departs from traditional fibers where the profile dispersion parameter monotonically decreases around the selected wavelength that maximizes the effective modal bandwidth (EMB).
