1. A fiber optic cable having a diameter in the range of 2.8-3.2 millimeters and comprising:
- a polymer jacket having a channel therein with a height in the range of 0.6-1.4 millimeters;
at least one optical fiber in the channel;
a strength material disposed within the channel and contacting the at least one optical fiber;
a first electrical conductor on a first side of the channel; and
a second electrical conductor on a second side of the channel,wherein the first electrical conductor and the second electrical conductor are in the range of 24-28 American Wire Gauge (AWG) and the channel is arranged on a first axis that extends through the first and second electrical conductors,wherein the optical fiber is positioned in the channel and remains within the channel 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.

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.
