Abstract:
1. A fiber optic cable, comprising: a first optical fiber comprising a glass core and cladding, wherein the glass core is configured to provide controlled transmission of light through the fiber optic cable for high-speed data communication; a jacket having an interior surface that defines a conduit through which the first optical fiber extends, and further having an exterior surface that defines the outside of the fiber optic cable; and a second optical fiber that is integrated with the exterior surface of the jacket, wherein second optical fiber is integrated with the exterior surface of the jacket such that when the jacket is bent to an angle, the second optical fiber is oriented at the bend to receive light provided by an external light source directed toward the second optical fiber for transmission of the light by the second optical fiber, wherein the angle corresponds to a bend radius that is greater than the minimum bend radius of the first optical fiber, and wherein the second optical fiber has at least twice the attenuation of visible light of the first optical fiber.
