Abstract
Disclosed is a dispersion compensating optical fiber that includes a core surrounded by a cladding layer of refractive index &Dgr; . The core includes at least three radially adjacent regions, a central core region having &Dgr; a moat region having a refractive index &Dgr; and an annular ring region having a refractive index &Dgr; such that &Dgr; >&Dgr;c>&Dgr; The fiber exhibits a dispersion at 1550 which is less than −30 ps/nm/km, and a &kgr; value obtained by dividing the dispersion value by the dispersion slope which is between 40 and 100.
