ABSTRACT:
A DCF for compensating for the accumulated dispersion of a length of SMF in the C+L band window that includes a core surrounded by a cladding layer of refractive index Δc. The core includes at least three radially adjacent segments; a central core segment having a positive Δ1, a moat segment having a negative refractive index Δ2, and a ring segment having a positive refractive index Δ3, wherein Δ1>Δ3>Δc>Δ2. The DCF exhibits a negative dispersion slope of between −0.29 and −0.43 ps
m2/km at 1575 nm, and a total dispersion less than −96 and greater than −108 ps
m/km at 1575 nm. A transmission link including the combination of a SMF and the present invention DCF is also disclosed.
