Abstract
Described is a technique for the design and manufacture of MMFs. Designs are implemented so as to limit the maximum variation in z(r, λ) with respect to wavelength, where z(r, λ) is the dielectric constant weighted by the square of the wavelength. MMFs for use in CWDM applications are specifically described.
