Dispersion managed HOM multimode optical fibre.

摘要

The fiber (4) has a central core surrounded by an optical sheath. Optical fiber portions having positive chromatic dispersion alternate longitudinally with optical fiber portions having negative chromatic dispersion, for higher order modes. Each portion has low absolute value chromatic dispersion loss and raised effective surface, with wavelength of 1550 nanometer in the higher order mode. - An INDEPENDENT CLAIM is also included for an optical transmission system including a multimode optical fiber.
