Abstract
A method and a resulting communication cable is disclosed which provides multiple degrees of control of fluid wicking propensity within the interior of the cable by impregnating the cable with a sealing composition and curing the sealing composition therein. The cable includes a central strata, a penultimate strata and an ultimate strata concentrically disposed. The central strata includes a central signal transmission medium circumscribed by a dielectric having an etched exterior surface. The penultimate strata includes a braided conductor circumscribing the dielectric and an inner jacket surrounding the braided conductor and including an etched exterior surface. The penultimate strata further includes at least one non-continuous zone of sealing composition impregnated into the braided conductor and bonding with the etched exterior surface of the dielectric. The ultimate strata includes a braided sheath circumscribing the inner jacket and an outer jacket surrounding the braided sheath. The ultimate strata further includes an extended substantially continuous zone of sealing composition impregnated into the braided sheath and bonding with the etched exterior surface of the inner ja…
