Fiber-optic technology improves internet speed by utilizing light signals transmitted through thin glass fibers. Unlike traditional copper cables, which rely on electrical signals, fiber optics can carry data at much higher bandwidths over long distances without significant loss. This technology enables faster data transfer rates, higher capacity, and improved reliability in connectivity. Fiber-optic networks are less susceptible to electromagnetic interference, resulting in a more stable connection. As a result, they are increasingly favored for high-speed internet services, supporting the growing demand for bandwidth-intensive applications like streaming and cloud computing.
