Superabsorbent polymer materials: a high performance, cost-effective alternative to viscous filling and flooding compounds for optical cable

摘要

A great deal of practical experience with dry water-blocked cables has been presented in detail along with considerable feedback from the field. The discussion clearly shows the outstanding characteristics of swellable yarns and tapes and their real world (ie bottom line) benefits and points out some of the shortcomings with previous methods of cable water-blocking. Simply stated, superabsorbent polymer materials are safe, easy to apply, reduce overall cable manufacturing and installation costs and improve craft friendliness.
