TLDR
In this article, a dispersion and dispersion slope compensating optical fiber is provided with a refractive index profile with a central core segment having a positive relative refractive indices.Abstract:
A dispersion and dispersion slope compensating optical fiber (10) includes a segmented core (12, 14, 16, 18) and a cladding layer (20) wherein the refractive index profile is selected to provide a dispersion having a maximum deviation of less than 7 ps/nm-km over a wavelength band from 1550 nm to 1610 run. According to a further embodiment of the invention, a dispersion compensating optical fiber is provided having a refractive index profile with a central core segment having a positive relative refractive index; a depressed moat segment on a periphery of the central core segment having a relative refractive index that is more negative than -1.2 %; and an annular ring segment outward from the depressed moat segment having a relative refractive index that is greater than 1.2 %.read more
