Abstract
Disclosed is a dispersion compensating optical fiber that includes a refractive index profile selected to provide dispersion at 1550 nm of between −90 and −150 ps/nm/km; dispersion slope at 1550 nm of less than −1.5 ps/nm2/km; and kappa of between 40 and 95. The profile preferably has a core surrounded by a cladding layer of refractive index Δc, and at least three radially adjacent regions including a central core region having Δ1, a moat region having a refractive index Δ2, and an annular ring region having a refractive index Δ3, wherein Δ1>Δ3>Δc>Δ2.
Claims13
A dispersion compensating optical fiber, comprising:
- a refractive index profile selected to provide
- a dispersion at 1550 nm between −90 and −150 ps/nm/km;
- a dispersion slope at 1550 nm of less than −1.5 ps/nm2/km;
- and
- a kappa value, obtained by dividing the dispersion at 1550 nm by the dispersion slope at 1550 nm, of between 40 and 95.
