OPAC (optical power attached cable) is a type of fiber optic cable that is installed by attaching to a host conductor along overhead power lines. For monitoring and managing networks, they use a variety of means of communications, including running fiber optic cables along the transmission and distribution towers, radio links and contracting landline and cellular communications services from telecom carriers. Utilities build fiber optic. Utility companies are using fiber optics more frequently in their everyday operations to monitor systems within the grid including power plants, substations, control centers, and distribution centers. These cables are made up of extremely thin strands of glass or plastic, known as optical fibers, which are encased in protective sheathing. Most aerial fiber optic cables are installed by lashing to a steel messenger wire strung between poles, but there is a category of cables with special high-strength jacket designs called all-dielectric self-supporting (ADSS). Fiber optic cables use light to transmit data, whereas traditional cables rely on electrical signals, which are more prone to interference and loss over distance.
