Abstract
A dispersion compensating fiber is described having a core and cladding as well as methods for making such fiber. The cladding has a first cladding region surrounding the core, a second cladding region surrounding the first cladding region, and a third cladding region surrounding the second cladding region. The core, and the first, second, and third cladding regions are doped to create a refraction index profile characteristic of dispersion compensating fiber. The core is doped with germanium, the first cladding region is doped with fluorine, and the second cladding region is doped with germanium and fluorine. A portion of the cladding is doped with phosphorus, thereby resulting in splice loss reduction.
