Methods of selecting optical fibers that meet bandwidth requirements at different wavelengths

A method of selecting from a set of optical fibers a subset of optical fibers that meet a short-wavelength bandwidth requirement BWRS at a short-wavelength λS and a target-wavelength bandwidth requirement BWRT at a target wavelength λT>λS, the method comprising:

• a) obtaining a short-wavelength bandwidth BWS from DMD measurement data at the short wavelength λS;
• b) determining a peak wavelength λP for each optical fiber;
• c) calculating a target-wavelength bandwidth BWT using the determined peak wavelength;
• d) identifying a peak wavelength threshold λPT from the determined peak wavelengths of the optical fibers in the set of optical fibers;
• and
• e) selecting, from the set of optical fibers, those optical fibers that have a peak wavelength λP≥λPT and a short-wavelength bandwidth BWS≥BWRS.
