Description
Summary:With the availability of single-mode optical fibers, information transmission is being revolutionized. There are primarily 3 different options available for an electric utility to choose a cable for signal transmission: 1. optical-fiber ground wire or optical-fiber phase wire, 2. wrapped systems, and 3. all-dielectric fiber-optic self-supporting cable. It appears that, for successfully deploying fiber-optic cables as communication links, using the existing transmission corridors, a fiber-optic telecommunication cable with a nonconductive strength member is an attractive option. This design has many advantages, including the isolating capability of the cables combined with low weight and small diameter and the ability for hot-line installation, which are valuable features in regard to high-voltage power lines.
