<p>A single mode dispersion and dispersion slope compensating optical fiber (10) includes a central core segment (12), a depressed moat segment (14), an annular ring segment (16), and a cladding layer (18). Each of the segments of the fiber have a relative refractive index that are selected to provide negative dispersion at a wavelength of within the range of about 1530 nm to about 1620 nm, negative dispersion slope at a wavelength of within the range of about 1530 nm to about 1620 nm, a kappa which is defined as the ratio of the dispersion to the dispersion slope value of within the range of 40 to about 60 at a wavelength of about 1550 nm, and a fiber cut-off wavelength of less than about 1650 nm, and more preferably less than 1550 nm.</p> |
