ABSTRACT:
A two-pole ruggedized optical fiber cable suitable for use in communication applications is described. The cable has a core assembly comprising a sealed inner copper alloy tube in which at least one optical fiber is encapsulated. Surrounding the core assembly is a layer of dielectric material, an outer metallic tube and, if needed, a protective jacket. The outer tube's primary function is to serve as the cable's primary strength member. The outer tube is preferably formed from a high strength, non-ferrous alloy having a relatively low modulus of elasticity. The outer tube is preferably a drawn tube having a substantially straight axial seam. If added hermeticity is required, the outer tube seam may be sealed. A process and apparatus for fabricating the cable is also described.
