Optical Ground Wire (OPGW): OPGW is a specialized type of cable extensively utilized in electric power transmission lines that operate above 50 kV. It combines the dual functions of providing overhead static grounding and lightning protection with telecommunications. Fiber optic cables enable high-speed, long-distance data transfer, forming the backbone of modern communication. Yet, outdoors, they face temperature swings, moisture, UV exposure, rodents, and human interference. Protecting them is essential for long-term reliability. This guide covers how to. Recommendation ITU-T L. It deals with the factors that should be considered in determining the characteristics of this type of cable, the apparatus that should be used, the precautions that should be taken in handling the reels, and. An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines.
