NOVEL COMPACT LOOSE TUBE CABLE INCORPORATING EVOLVED DRY WATERBLOCKING METHOD

摘要

Cable constructions with dry core designs have been introduced to provide field personnel with craft-friendly and cost effective methods of accessing the cable core for reentries and mid-span access. The novelty of the cable introduced in this paper lies in its function for indoor and outdoor use and its compactness, i.e. decreased cable weight and diameter. The cable still retains its ease of connectorization through the use of standard loose tube fan-out kits for rapid, simple termination. The paper introduces a new method to waterblock a loose tube design using swellable impregnated fiberglass yarns.
