A water-swellable material is included for water-blocking inside a buffer tube in a cable design, and an adhesive material is provided in or on the water-swellable material. The adhesive material may function as a bonding agent between the water-swellable material and the inside wall of a buffer tube, thus providing coupling of the water-swellable material to the buffer tube. In addition, or alternatively, a second adhesive material may be provided for bonding the optical fibers to the water-swellable material. The adhesive materials may be in the form of a bead or beads and may be foamed or unfoamed.
