1. A fiber optic cable, comprising:
- at least one optical fiber, the at least one optical fiber being a microstructured bend performance optical fiber; and
a protective covering, the protective covering being highly flexible and the fiber optic cable has a delta attenuation of about 0.33 dB or less when wrapped 3 turns about a 7.5 millimeter diameter mandrel at a reference wavelength of 1625 nanometers.

Abstract
A fiber optic cable having at least one optical fiber such as a microstructured bend performance optical fiber disposed within a protective covering. The protective covering is highly flexible and the fiber optic cable has extremely low delta attenuation when aggressively bent compared with the conventional fiber optic cable designs. By way of example, the delta attenuation of one fiber optic cable design is about 0.33 dB or less when wrapped 3 turns about a 7.5 millimeter mandrel at a reference wavelength of 1625 nanometers. Other variations of the present invention include a connector attached to the fiber optic cable.
