Armored flexible fiber optic assembly

Abstract

The specification relates to a fiber optic cable assembly. The fiber optic cable assembly includes a non-interlocking armor, the non-interlocking armor is a spiral tube having an outside diameter of approximately 1.5 mm-5.5 mm, an inner diameter of approximately 0.75 mm-5.25 mm and a minimum bend radius of approximately 5 mm, the non-interlocking armor being formed from stainless steel; an inner jacket, the inner jacket having an outside diameter slightly less than the inner diameter of the non-interlocking armor; at least one fiber optic fiber; and a strengthening material, the strengthening material being made from aramid fibers and surrounding the at least one fiber optic fiber underneath the inner jacket.

1 . A fiber optic cable assembly comprising:
 a non-interlocking armor, the non-interlocking armor is a spiral tube having an outside diameter of approximately 1.5 mm-5.5 mm, an inner diameter of approximately 0.75 mm-5.25 mm and a minimum bend radius of approximately 5 mm, the non-interlocking armor being formed from stainless steel;   an inner jacket, the inner jacket having an outside diameter slightly less than the inner diameter of the non-interlocking armor;   at least one fiber optic fiber; and   a strengthening material, the strengthening material being made from aramid fibers and surrounding the at least one fiber optic fiber underneath the inner jacket.   
     
     
         2 . The fiber optic cable assembly of  claim 1  further comprising:
 an outer jacket, the outer jacket having an inside diameter slightly greater than the outside diameter of the non-interlocking armor; and 
 a pull material, the pull material being made from aramid fibers, the pull material being positioned underneath the outer jacket and on top of the non-interlocking armor. 
 
     
     
         3 . The apparatus of  claim 1  wherein the non-interlocking armor has a gap between each spiraling ring, the gap is approximately 0.05 mm to 1 mm. 
     
     
         4 . The apparatus of  claim 1  wherein the non-interlocking armor has a thickness of approximately 0.25 mm-0.75 mm. 
     
     
         5 . The apparatus of  claim 1  wherein the non-interlocking armor has a crush resistance of approximately ≥100 KGf/100 mm. 
     
     
         6 . The fiber optic cable assembly of  claim 1  wherein the fiber optic cable assembly has an outside diameter of approximately 1.65 mm to 5.5 mm. 
     
     
         7 . The apparatus of  claim 1  wherein the at least one fiber optic fiber is a 62.5/125 μm multimode fiber. 
     
     
         8 . The apparatus of  claim 1  wherein the at least one fiber optic fiber is a 50/125 μm 10G OM3/OM4 fiber. 
     
     
         9 . The apparatus of  claim 1  wherein the at least one fiber optic fiber is a 9/125 μm single mode G652.D fiber. 
     
     
         10 . The apparatus of  claim 1  wherein the at least one fiber optic fiber is an 80/125 μm single mode bend-insensitive fiber.
