Abstract
A fiber optic ribbon cable includes a stack of fiber optic ribbons, strength members surrounding the stack, and a jacket defining an exterior of the cable. The jacket forms a cavity through which the stack and the strength members extend. The stack has a bend preference, but the strength members are positioned around the stack or are flexible in bending such that the strength members do not have a bend preference. Furthermore, the jacket is structured such that the jacket does not have a bend preference. The cavity is sized relative to the stack in order to allow the stack to bend and twist within the cavity with respect to the jacket as the cable bends, facilitating movement of the optical fibers of the fiber optic ribbons to low-stress positions within the cavity and decoupling the bend preference of the stack from transfer to the jacket.
