ODN and passive infrastructure knowledge brief Published 11 May 2022

Prepared for preliminary research by the GESTIONVAL ODN knowledge desk. Confirm network topology, split ratio, box or cabinet capacity, joint closure rating and loss budget against current standards and product documentation.

The most commonly used optical cables in power communication are OPGW, OPPC, ADSS, and OPAC, each designed to integrate fiber optics with power transmission infrastructure.Optical Power Ground Wire (OPGW)

OPGW combines optical fibers with a metallic ground wire, typically installed at the top of transmission towers. It serves dual purposes: lightning protection for the power line and high-speed data transmission through embedded singlemode fibers. The fibers are housed in a sealed metal tube surrounded by steel strength members and aluminum conductors, ensuring immunity to electrical interference while maintaining mechanical and electrical performance standards. OPGW is widely used in both new and retrofitted lines .

Optical Power Phase Conductor (OPPC)

OPPC integrates optical fibers directly into the phase conductors of power lines. Unlike OPGW, which is installed as a ground wire, OPPC utilizes existing phase line resources, allowing efficient use of the transmission line for communication purposes. It provides similar optical performance to OPGW while maintaining the mechanical and electrical integrity of the conductor. OPPC is particularly useful in high-voltage systems where maximizing line utility is critical .

All-Dielectric Self-Supporting (ADSS) Cable

ADSS cables are fully dielectric, meaning they contain no metallic components, making them ideal for installation near high-voltage lines without risk of electrical conduction. They are self-supporting and can be mounted on towers or poles, providing strong resistance to magnetic interference, electric corrosion, and environmental stress. ADSS cables are commonly used in transmission lines of 35kV, 110kV, and 220kV, offering reliable optical performance in harsh outdoor conditions .

Optical Power Attached Cable (OPAC)

OPAC is a lightweight, all-dielectric fiber optic cable designed to be wrapped around existing power or ground conductors. Installation is typically done using a "Sky-Wrap" method, allowing the cable to follow the conductor along spans exceeding 2 km and tower heights over 200 meters. OPAC is suitable for expanding communication capacity on existing lines without major infrastructure changes. Its loose tube design and abrasion-resistant jacket ensure fiber protection under mechanical stress and environmental exposure .

Summary of Applications
  • OPGW: New or retrofitted lines, lightning protection, high-speed communication.
  • OPPC: Utilizes phase conductors for communication, efficient line resource use.
  • ADSS: Non-metallic, self-supporting, suitable for high-voltage lines with strong environmental resilience.
  • OPAC: Lightweight, attachable to existing conductors, ideal for capacity expansion. These optical cables enable reliable, high-speed communication across power transmission networks while maintaining safety, mechanical integrity, and resistance to electrical interference, making them essential for modern power system monitoring and control .
