Abstract An optical fiber cable which is constructed so as to minimize optical transmission loss, and which comprises one or more compliant core units retained within a surrounding sheath. Each compliant core unit is composed of a bundle of parallel optical fibers, such as a stack of ribbons, enclosed in and supported by a compliant unitizing structure. The structure may derive its compliance from a foamed material, such as polyethylene, that is extruded to surround the fiber bundle. The foam material sufficiently cushions the bundle of fibers from external stresses that are applied when the cable is bent or encounters compressive loading.
