Self-supporting, metal free, optical cable for long-span, power line use

The authors review the design, development and application of a particular design of self supporting metal-free, optical cable for data and telephony transmission, for use on power lines with long spans. The authors also describe significant advances in design and installation techniques and report experimental and operational results which enhance confidence in this technology, which is of growing interest to overhead line and telecommunication engineers. It is concluded that this cable type can be safely and economically operated on long-span, overhead distribution lines
