- Quadruply clad fiber
fiber optics, a quadruply clad fiber is a single-mode optical fiberthat has four claddings. Each claddinghas a refractive indexlower than that of the core. With respect to one another, their relative refractive indices are, in order of distance from the core: lowest, highest, lower, higher.
A quadruply clad fiber has the advantage of very low macrobending losses. It also has two zero-dispersion points, and moderately low dispersion over a wider
wavelengthrange than a singly clad fiber or a doubly clad fiber.
