When did everyone start using fiber optics?

The widespread adoption of fiber optics began in the 1980s, primarily for telecommunications and data transmission. The technology became commercially viable with the development of low-loss fiber and the introduction of optical amplifiers, which significantly improved signal quality over long distances. By the 1990s, fiber optics were being increasingly integrated into telecommunications infrastructure, leading to the rapid expansion of internet and communication services. Today, fiber optics are essential for high-speed internet and various communication technologies.
