Abstract
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.
