ABSTRACT:
A robust fiber optic cable is well suited for harsh environments, such as undersea environments, as a communication link to a mobile undersea vehicle. In preferred embodiments, the fiber optic cable is constructed to have neutral buoyancy in salt water. The fiber optic cable may include one single mode optical fiber. A suspension fluid, such as light mineral oil surrounds the optical fiber. In an optional embodiment, a plurality of strength members also surrounds the optical fiber and these elements are surrounded by an outer jacket. In another optional embodiment, the optical fiber and suspension fluid may be loosely surrounded by an inner containment tube, a plurality of strength members surrounds the inner containment tube, and these elements are surrounded by an outer jacket, which may be bonded to the inner containment tube.
