Title:
DISPERSION SLOPE COMPENSATING OPTICAL FASER
Document Type and Number:
WIPO Patent Application WO2001071391
Kind Code:
A9
Abstract:
Disclosed is a dispersion compensating optical fiber that includes a core surrounded by a cladding layer of refractive index DELTA c. The core includes at least three radially adjacent regions, a central core region having DELTA 1, a moat region having a refractive index DELTA 2 and an annular ring region having a refractive index DELTA 3, such that DELTA 1 > DELTA 3 > DELTA c > DELTA 2. The fiber exhibits a dispersion slope which is less than -1.0 ps/nm<2>/km over the wavelength range 1525 to 1565, a dispersion at 1550 which is less than -30 ps/nm/km, and a kappa value obtained by dividing the dispersion value by the dispersion slope which is greater than 35 and preferably between 40 and 100.
