Abstract : A review of the evolution of cable designs and materials shows the difficulty of predicting service life exceeding 20 years based on short term tests. This has been particularly true for the polymeric components of telecommunication cables. When problems were encountered with weathering, environmental cracking, and notch sensitivity, changes were successfully made. A brief history of the development of the polyolefin insulated and jacketed telephone cables will form the basis for a review of the key material and cable properties needed to produce a cable capable of service exceeding 20 years.
