This presentation from The Fiber Optic Association discusses fiber optic communications. It explains that fiber optic technology transmits communications signals over thin strands of glass or plastic, and has been used commercially since 1980, though the concept is over a century old. The presentation outlines how fiber optic technology works using the principle of total internal reflection to contain light within the core of the fiber. It also provides examples of fiber optic applications for both outside plant and premises installations and discusses career opportunities in the fiber optics industry, including manufacturing, installation, design, and teaching.
