MULTIMODE OPTICAL FIBERS AND METHODS OF MANUFACTURE THEREOF

摘要

The present invention generally relates to the field of fiber optics, and more specifically to optical fibers, methods of manufacturing optical fibers, and methods of classifying optical fibers. In an embodiment, the present invention is a multimode optical fiber which comprises a core and clad material system where the refractive indices of the core and cladding are selected to minimize chromatic dispersion in the 850 nm wavelength window and the refractive index profile is optimized for minimum modal-chromatic dispersion in channels utilizing VCSEL transceivers. Multimode optical fibers according to this embodiment may have increased channel bandwidth.

主权项

1. A multimode optical fiber comprising:
a cladding having a refractive index n1; and a core at least partially surrounded by said cladding,
said core having a refractive index profile optimized to operate within a single wavelength operating window,said core further having a center, said center of said core having a refractive index n0, wherein(n02-n12)2n02≈0.01,and
wherein said core comprises at least one dopant, said at least one dopant reducing a zero dispersion wavelength of said multimode optical fiber below 1295 nanometers (nm), and wherein said multimode optical fiber does not support operation outside of said single wavelength operating window.
