Polymer-coated transmission media having water-blocking material embedded in the outer surface of the transmission media prevents water penetration into the transmission media and reduces the overall diameter of a cable made from the transmission media by eliminating a water-blocking tape layer in the cable. The outer surface of the transmission media is a polymer whose outer surface is embedded with a water-blocking material. The water-blocking material is applied before the polymer is cured. The transmission media may be any known type of optical media, which guides a light within the optical media. In various embodiments, optical fibers, buffered optical fibers and fiber ribbons are used as the transmission media.
