Abstract
A method of qualifying an effective bandwidth of a multimode optical fiber at a first wavelength λ, using DMD data of the fiber measured a second wavelength λ. Data representative of a Radial Offset Delay, a Radial Offset Bandwidth and a Relative Radial Coupled Power of the fiber are derived from the DMD data at the second wavelength λ. A transformation is performed on the ROD data and ROB data at the second wavelength λto obtain corresponding ROD data and ROB data at the first wavelength λ. An effective bandwidth of the fiber at the second wavelength λis computed using the ROD data and the ROB data at the first wavelength λand the {tilde over (P)}data at the second wavelength λ.
