A cable including an outer metal tube and a first layer wire inside the outer metal tube, wherein the first layer wire has five inner elements surrounding a metallic center member and at least one of the inner elements is a metal tube containing an optical fiber.
First claim
Opening claim text (preview).
What is claimed is: 1. A cable, comprising: an outer metal tube; and a first layer wire inside said outer metal tube; wherein said first layer wire consists of five metallic inner elements surrounding a solid metallic center member; wherein at least a first one of said metallic inner elements is a metal tube containing containing an optical fiber, and wherein at least a second one of said metallic inner elements is free from optical fibers and is a metal tube with a metal filler. 2. The cable of claim 1 , wherein said outer tube comprises stainless steel. 3. The cable of claim 1 , wherein at least one of said inner elements comprises stainless steel. 4. The cable of claim 1 , wherein said cable has zero fiber strain up to at least approximately 600 degrees C. 5. The cable of claim 1 , wherein four of said inner elements are metal tubes with metal fillers. 6. The cable of claim 1 , wherein the five inner elements are helically wound around the metallic center member. 7. A cable, comprising: an outer metal tube; and a first layer wire inside said outer metal tube; wherein said first layer wire consists of three metallic inner elements; wherein at least a first one of said metallic inner elements is a metal tube containing an optical fiber, and wherein at least a second one of said metallic inner elements is free from optical fibers and is a metal tube with a metal filler. 8. The cable of claim 7 , wherein said outer tube comprises stainless steel. 9. The cable of claim 7 , wherein at least one of said inner elements comprises stainless steel. 10. The cable of claim 7 , wherein said cable has zero fiber strain up to at least approximately 600 degrees C. 11. The cable of claim 7 , wherein two of said inner elements are metal tubes with metal fillers. 12. The cable of claim 7 , wherein the three inner elements are helically wound.
