Abstract

Disclosed is a fiber optic cable that includes optical fibers and a water-swellable element, such as a powder-free fabric tape, that are enclosed within a buffer tube. Adhesive material, such as discrete domains of adhesive foam, may be optionally employed to provide adhesive coupling of the optical fibers and the water-swellable element.
