1. A fiber optic cable comprising:
- a polymer jacket having a channel therein, the channel having a first slot;
at least one optical fiber in the first slot;
a first electrical conductor; and
a second electrical conductor,wherein the optical fiber is positioned in the first slot and remains within the first slot when the fiber optic cable is bent a maximum amount such that a bend radius of the optical fiber is greater than or equal to a minimum bend radius of the optical fiber;
wherein the cable has a diameter in the range of 2.8-3.2 millimeters;
wherein the first slot is arranged on a first axis, and a second axis extends through the first and second electrical conductors; and
wherein the cable has a preferential bend axis of minimum bend moment of inertia about the second axis.

Abstract
Methods of controlling the position of an optical fiber having a minimum bend radius within an optical fiber channel in a fiber optic cable having a small footprint are disclosed. The position of the optical fibers is controlled so that the fiber is not bent at a radius below its minimum bend radius.
