While electricity itself is not transmitted through fiber optic cables, this technology is a vital part of modern power transmission. The term most often refers to the use of a specialized cable called Optical Ground Wire (OPGW). OPGW serves a dual purpose: it acts as a traditional ground wire on top of high-voltage transmission towers, protecting the power lines from lightning strikes, and it simultaneously houses fiber optic strands for high-speed data communication. This integration is crucial for building smart grids and ensuring reliable, real-time monitoring and control of the power network.
