Abstract
A fiber optic cable includes a first optical fiber, a jacket, and a second optical fiber. The first optical fiber includes a glass core and cladding. The glass core is configured to provide controlled transmission of light through the fiber optic cable for high-speed data communication. The jacket has an interior surface that defines a conduit through which the first optical fiber extends. The jacket further has an exterior surface that defines the outside of the fiber optic cable. The second optical fiber is integrated with the exterior surface of the jacket.

A method of manufacturing a cable, comprising:
- extruding a second optical fiber, wherein the second optical fiber is plastic, and wherein the second optical fiber is configured to release, along a length of the second optical fiber, at least some of light passed through the second optical fiber;
- and
- extruding, while extruding the second optical fiber, a jacket to at least partially embed the second optical fiber and to surround a first optical fiber, the first optical fiber comprising a glass core and cladding, wherein the glass core is configured to provide controlled transmission of light therethrough for high-speed data communication;
- wherein the first optical fiber is positioned in an interior cavity of the jacket and the second optical fiber is integrated with an exterior surface of the jacket, and wherein the jacket is such that light released by the second optical fiber is visible along the exterior surface of the jacket, thereby providing a visual trace.
A method of manufacturing a cable, comprising:
- extruding a jacket to surround a first optical fiber, the first optical fiber comprising a glass core and cladding, wherein the glass core is configured to provide controlled transmission of light therethrough for high-speed data communication;
- and
- co-extruding a second optical fiber with the jacket such that the second optical fiber is at least partially embedded in the jacket, wherein the second optical fiber is plastic, and wherein the second optical fiber is configured to release, along a length of the second optical fiber, at least some of light passed through the second optical fiber such that the released light is visible along the exterior surface of the jacket, thereby providing a visual trace.
