摘要
Embodiments of an optical fiber cable are provided. The cable includes a cable jacket and at least one buffer tube. Each buffer tube surrounds a plurality of optical fibers. The cable jacket surrounds the at least one buffer tube. Further, a coating of superabsorbent, swellable hot melt is applied to at least one of the following locations: (i) along at least a portion of the length of at least one of the plurality of optical fibers; (ii) along at least a portion of the length of the exterior or interior surface of the at least one buffer tube; or (iii) along at least a portion of the length of the interior surface of the cable jacket. Moreover, the superabsorbent, swellable hot melt is capable of absorbing at least 50 g of water per gram of superabsorbent, swellable hot melt.
