Abstract
Fiber optic cables, and methods of manufacturing the same, include a plurality of carriers having at least one optical fiber therein. In one embodiment, the carriers are arranged in two layers within the cable and are generally disposed about a center area of the cable. Each layer has a respective helix-plus-EFL value. A difference between the respective helix-plus-EFL values of the layers defines a differential range being, preferably, about 1% or less. Additionally, the fiber optic cables can be used in fiber optic cable systems such as dispersion managed cable systems (DMCS).
