An optical fiber cable is provided for undersea applications that include a hollow buffers tube with at least one optical fiber disposed therein. The buffer tube is formed from a plastic material. A water-blockable gel is located in the buffer tube and a series of strength members are configured in a close-packed arrangement around the buffer tube. A metal conductor surrounds the series of strength members and a plastic jacket encapsulating the metal conductor.

An optical fiber cable structure includes a central kingwire and a plurality of fibers disposed to surround the kingwire. Microbending losses are accommodated by surrounding each individual fiber with a thin gel layer. The plurality of fibers are embedded in a solid (rubbery) polymer to provide the required strength. In one embodiment, the central cable structure is further surrounded by a layer of foamed polymer to provide for an absorbing interface between the solid polymer and the steel wire strands surrounding the cable structure.
