Abstract

A communications cable and method for making same wherein a communications cable is able to withstand significantly higher thermal temperatures than conventional fiber whether it be general purpose, or rated as Plenum/Riser rating, or even MIL Spec type cables. A core fiber glass material with at least an 800 Fahrenheit degree operating ability allows the communications cable to survive in high heat or stress conditions. A polyimide coating on the outside of the fiber is a high temperature material and lends to this high operating temperature capability. By containing and protecting an optical pair of these fibers or even up to 4 glass fibers within a silicone rubber 1 mm diameter buffer tube, thermal protection of the high temperature glass within is increased. A single buffer tube type product and market that as a mini solution for fiber optic requirements within equipment or we individually or group wise mechanically protect these buffer tubes. The choice and decision to apply 2 layers of opposing woven aramid/KEVLAR™ fibers now begins to apply a enhance tensile strength capability resulting in significant increase of currently available fiber optic cables. Once this mechanical protection layer has been applied a second, but thicker layer of silicone rubber is applied as an outer protection jacket either over the single paired Duplex Cable or the 24 Pair or larger cable design.

Claims

1. A communications system providing a fault-tolerant communications path for narrow and broad band communication comprising:

one or more self-powered satellite units each providing signal information to at least one command console through a segmented cable assembly system;

a central station that receives signal information from the at least one command console and relays signal information back to the command console wirelessly and via the segmented cable assembly system.

2. The communication system of claim 1, wherein the segmented cable assembly system is powered by a controller outfitted with a transceiver and an external high gain antenna.

3. The communication system of claim 1, wherein the segmented cable assembly system includes a repeater.

4. The communications system of claim 1, wherein the segmented cable assembly system includes a UWB radio and antenna.

5. A cable assembly comprising:

one or more fixed length cable segments, each segment linked to a junction box having a repeater system to extend a signal communications range significantly further than 3000 feet.

6. The cable assembly of claim 5, wherein the each segment includes a metal casing and core bundle wrapped with an aerogel material.

7. The cable assembly of claim 5, wherein each segment includes a stress release system, each segment configured for 2600 pounds of longitudinal force.

8. The cable assembly of claim 5, wherein each segment will re-broadcast a signal selected from the group consisting of UWB, WiFi and RF.

9. The cable assembly of claim 5, wherein the cable assembly has no vertical or horizontal constraints.

10. The cable assembly of claim 5, wherein each segment will withstand temperatures in excess of current plenum and riser wiring standards.

11. The cable assembly of claim 5, wherein the junction box has plug-in circuit board.

12. The cable assembly of claim 5, wherein the junction box includes a raceway system to drop splice fiber optic channels for direct plug-in to one or more circuit board media converters.

13. The cable assembly of claim 5, wherein the junction box includes a thermal cooling system operable with an on-board CPU to prevent overheating and failure.

14. The cable assembly of claim 5, wherein the junction box is controlled by a separate controller.

15. A cable assembly comprising:

one or more fixed length cable segments, each segment capable of withstanding temperatures in excess of current plenum and riser wiring standards, wherein each segment includes a high gauge metal casing and a core bundle wrapped with a heat resistant aerogel material.

16. The cable assembly of claim 15, wherein the core bundle includes one or more power conductors, one or more multi-mode fiber optic data channels, a coaxial cable and a high stress cable.
