FIBER OPTIC RIBBON CABLE

摘要

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.

1. A fiber optic ribbon cable, comprising:
a stack of fiber optic ribbons having a bend preference; strength members surrounding the stack of fiber optic ribbons, wherein the strength members are at least one of positioned around the stack and flexible in bending such that the strength members do not have a bend preference; and a jacket defining an exterior of the fiber optic ribbon cable, wherein the jacket forms a cavity through which extends the stack of fiber optic ribbons and the strength members; and wherein the jacket is structured such that the jacket does not have a bend preference; and wherein the cavity of the jacket is sized relative to the stack of fiber optic ribbons 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.
