Abstract
A reduced dispersion optical waveguide and methods of fabricating the same are implemented. The optical waveguide may be fabricated in commercially practicable units without having to predetermine its length in a particular application. The reduced dispersion optical waveguide prevents optical pulse overlap in optical waveguide transmission systems operating over long distances or at high data rates.
