Patent ID: 6873798

Claim:
An apparatus, comprising: an optical sublink including an operationally coupled plurality of optical fiber segments, the plurality of optical fiber segments being from a first optical fiber type, a second optical fiber type and a third optical fiber type, the first optical fiber type having a dispersion and a dispersion slope, the second optical fiber type having a dispersion and a dispersion slope substantially equal in magnitude to and opposite signed from the dispersion and the dispersion slope of the first optical fiber type, the third optical fiber type having a dispersion opposite signed from the dispersion of the first optical fiber type and having a dispersion slope opposite signed from the dispersion slope of the second optical fiber type, wherein the plurality of optical fiber segments define a plurality of link spans including a first link span, the first link span having a first optical fiber segment and a second optical fiber segment from the plurality of optical fiber segments, the first optical fiber segment of the first link span being the first optical fiber type the second optical fiber segment of the first link span being the second optical fiber type.
